Fixed a signed integer overflow and subsequent segfault that occurred when +attempting to decompress images with more than 715827882 pixels using the +64-bit C version of TJBench. + +3. Fixed out-of-bounds write in `tjDecompressToYUV2()` and +`tjDecompressToYUVPlanes()` (sometimes manifesting as a double free) that +occurred when attempting to decompress grayscale JPEG images that were +compressed with a sampling factor other than 1 (for instance, with +`cjpeg -grayscale -sample 2x2`). + +4. Fixed a regression introduced by 2.0.2[5] that caused the TurboJPEG API to +incorrectly identify some JPEG images with unusual sampling factors as 4:4:4 +JPEG images. This was known to cause a buffer overflow when attempting to +decompress some such images using `tjDecompressToYUV2()` or +`tjDecompressToYUVPlanes()`. + +5. Fixed an issue, detected by ASan, whereby attempting to losslessly transform +a specially-crafted malformed JPEG image containing an extremely-high-frequency +coefficient block (junk image data that could never be generated by a +legitimate JPEG compressor) could cause the Huffman encoder's local buffer to +be overrun. (Refer to 1.4.0[9] and 1.4beta1[15].) Given that the buffer +overrun was fully contained within the stack and did not cause a segfault or +other user-visible errant behavior, and given that the lossless transformer +(unlike the decompressor) is not generally exposed to arbitrary data exploits, +this issue did not likely pose a security risk. + +6.

-<p>TurboJPEG API. </p> -<p>This API provides an interface for generating, decoding, and transforming planar YUV and JPEG images in memory.</p> -<p><a class="anchor" id="YUVnotes"></a></p> -<h2>YUV Image Format Notes</h2> -<p>Technically, the JPEG format uses the YCbCr colorspace (which is technically not a colorspace but a color transform), but per the convention of the digital video community, the TurboJPEG API uses "YUV" to refer to an image format consisting of Y, Cb, and Cr image planes.</p> -<p>Each plane is simply a 2D array of bytes, each byte representing the value of one of the components (Y, Cb, or Cr) at a particular location in the image. The width and height of each plane are determined by the image width, height, and level of chrominance subsampling. The luminance plane width is the image width padded to the nearest multiple of the horizontal subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of 4:1:1, 1 in the case of 4:4:4 or grayscale.) Similarly, the luminance plane height is the image height padded to the nearest multiple of the vertical subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4 or grayscale.) This is irrespective of any additional padding that may be specified as an argument to the various YUV functions. The chrominance plane width is equal to the luminance plane width divided by the horizontal subsampling factor, and the chrominance plane height is equal to the luminance plane height divided by the vertical subsampling factor.</p> -<p>For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is used, then the luminance plane would be 36 x 35 bytes, and each of the chrominance planes would be 18 x 35 bytes. If you specify a line padding of 4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and each of the chrominance planes would be 20 x 35 bytes. </p> -<h2 class="groupheader">Macro Definition Documentation</h2> -<a class="anchor" id="ga39f57a6fb02d9cf32e7b6890099b5a71"></a> -<div class="memitem"> -<div class="memproto"> - <table class="memname"> - <tr> - <td class="memname">#define TJ_NUMCS</td> - </tr> - </table> -</div><div class="memdoc"> - -<p>The number of JPEG colorspaces. </p> - -</div> -</div> -<a class="anchor" id="ga79bde1b4a3e2351e00887e47781b966e"></a> -<div class="memitem"> -<div class="memproto"> - <table class="memname"> - <tr> - <td class="memname">#define TJ_NUMERR</td> - </tr> - </table> -</div><div class="memdoc"> - -<p>The number of error codes. </p> - -</div> -</div> -<a class="anchor" id="ga7010a4402f54a45ba822ad8675a4655e"></a> -<div class="memitem"> -<div class="memproto"> - <table class="memname"> - <tr> - <td class="memname">#define TJ_NUMPF</td> - </tr> - </table> -</div><div class="memdoc"> - -<p>The number of pixel formats. </p> - -</div> -</div> -<a class="anchor" id="ga5ef3d169162ce77ce348e292a0b7477c"></a> -<div class="memitem"> -<div class="memproto"> - <table class="memname"> - <tr> - <td class="memname">#define TJ_NUMSAMP</td> - </tr> - </table> -</div><div class="memdoc"> - -<p>The number of chrominance subsampling options. </p> - -</div> -</div> -<a class="anchor" id="ga0f6dbd18adf38b7d46ac547f0f4d562c"></a> -<div class="memitem"> -<div class="memproto"> - <table class="memname"> - <tr> - <td class="memname">#define TJ_NUMXOP</td> - </tr> - </table> -</div><div class="memdoc"> - -<p>The number of transform operations. </p> - -</div> -</div> -<a class="anchor" id="gacb233cfd722d66d1ccbf48a7de81f0e0"></a> -<div class="memitem"> -<div class="memproto"> - <table class="memname"> - <tr> - <td class="memname">#define TJFLAG_ACCURATEDCT</td> - </tr> - </table> -</div><div class="memdoc"> - -<p>Use the most accurate DCT/IDCT algorithm available in the underlying codec. </p> -<p>The default if this flag is not specified is implementation-specific.

The Java front end for this is defined in several classes -located under org/libjpegturbo/turbojpeg. The source code for these Java -classes is licensed under a BSD-style license, so the files can be incorporated -directly into both open source and proprietary projects without restriction. A -Java archive (JAR) file containing these classes is also shipped with the -"official" distribution packages of libjpeg-turbo. - -TJExample.java, which should also be located in the same directory as this -README file, demonstrates how to use the TurboJPEG Java API to compress and -decompress JPEG images in memory. - - -Performance Pitfalls --------------------- - -The TurboJPEG Java API defines several convenience methods that can allocate -image buffers or instantiate classes to hold the result of compress, -decompress, or transform operations. However, if you use these methods, then -be mindful of the amount of new data you are creating on the heap. It may be -necessary to manually invoke the garbage collector to prevent heap exhaustion -or to prevent performance degradation. Background garbage collection can kill -performance, particularly in a multi-threaded environment (Java pauses all -threads when the GC runs.) - -The TurboJPEG Java API always gives you the option of pre-allocating your own -source and destination buffers, which allows you to re-use those buffers for -compressing/decompressing multiple images. If the image sequence you are -compressing or decompressing consists of images of the same size, then -pre-allocating the buffers is recommended. - - -Installation Directory ----------------------- - -The TurboJPEG Java Wrapper will look for the TurboJPEG JNI library -(libturbojpeg.so, libturbojpeg.jnilib, or turbojpeg.dll) in the system library -paths or in any paths specified in LD_LIBRARY_PATH (Un*x), DYLD_LIBRARY_PATH -(Mac), or PATH (Windows.) Failing this, on Un*x and Mac systems, the wrapper -will look for the JNI library under the library directory configured when -libjpeg-turbo was built.

of its classes and interfaces, with a summary for each. This page can contain six categories:</p> -<ul> -<li>Interfaces (italic)</li> -<li>Classes</li> -<li>Enums</li> -<li>Exceptions</li> -<li>Errors</li> -<li>Annotation Types</li> -</ul> -</li> -<li class="blockList"> -<h2>Class/Interface</h2> -<p>Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:</p> -<ul> -<li>Class inheritance diagram</li> -<li>Direct Subclasses</li> -<li>All Known Subinterfaces</li> -<li>All Known Implementing Classes</li> -<li>Class/interface declaration</li> -<li>Class/interface description</li> -</ul> -<ul> -<li>Nested Class Summary</li> -<li>Field Summary</li> -<li>Constructor Summary</li> -<li>Method Summary</li> -</ul> -<ul> -<li>Field Detail</li> -<li>Constructor Detail</li> -<li>Method Detail</li> -</ul> -<p>Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</p> -</li> -<li class="blockList"> -<h2>Annotation Type</h2> -<p>Each annotation type has its own separate page with the following sections:</p> -<ul> -<li>Annotation Type declaration</li> -<li>Annotation Type description</li> -<li>Required Element Summary</li> -<li>Optional Element Summary</li> -<li>Element Detail</li> -</ul> -</li> -<li class="blockList"> -<h2>Enum</h2> -<p>Each enum has its own separate page with the following sections:</p> -<ul> -<li>Enum declaration</li> -<li>Enum description</li> -<li>Enum Constant Summary</li> -<li>Enum Constant Detail</li> -</ul> -</li> -<li class="blockList"> -<h2>Tree (Class Hierarchy)</h2> -<p>There is a <a href="overview-tree.html">Class Hierarchy</a> page for all packages, plus a hierarchy for each package.

A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</p> -</li> -<li class="blockList"> -<h2>Index</h2> -<p>The <a href="index-all.html">Index</a> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</p> -</li> -<li class="blockList"> -<h2>Prev/Next</h2> -<p>These links take you to the next or previous class, interface, package, or related page.</p> -</li> -<li class="blockList"> -<h2>Frames/No Frames</h2> -<p>These links show and hide the HTML frames. All pages are available with or without frames.</p> -</li> -<li class="blockList"> -<h2>All Classes</h2> -<p>The <a href="allclasses-noframe.html">All Classes</a> link shows all classes and interfaces except non-static nested types.</p> -</li> -<li class="blockList"> -<h2>Serialized Form</h2> -<p>Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API.

The TurboJPEG API allows both the JPEG compression and - decompression pipelines to be split into stages: YUV encode, compress from - YUV, decompress to YUV, and YUV decode. A <code>YUVImage</code> instance - serves as the destination image for YUV encode and decompress-to-YUV - operations and as the source image for compress-from-YUV and YUV decode - operations. - <p> - Technically, the JPEG format uses the YCbCr colorspace (which technically is - not a "colorspace" but rather a "color transform"), but per the convention - of the digital video community, the TurboJPEG API uses "YUV" to refer to an - image format consisting of Y, Cb, and Cr image planes. - <p> - Each plane is simply a 2D array of bytes, each byte representing the value - of one of the components (Y, Cb, or Cr) at a particular location in the - image. The width and height of each plane are determined by the image - width, height, and level of chrominance subsampling. The luminance plane - width is the image width padded to the nearest multiple of the horizontal - subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of - 4:1:1, 1 in the case of 4:4:4 or grayscale.) Similarly, the luminance plane - height is the image height padded to the nearest multiple of the vertical - subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4 - or grayscale.) The chrominance plane width is equal to the luminance plane - width divided by the horizontal subsampling factor, and the chrominance - plane height is equal to the luminance plane height divided by the vertical - subsampling factor. - <p> - For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is - used, then the luminance plane would be 36 x 35 bytes, and each of the - chrominance planes would be 18 x 35 bytes. If you specify a line padding of - 4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and - each of the chrominance planes would be 20 x 35 bytes.</div> -</li> -</ul> -</div> -<div class="summary"> -<ul class="blockList"> -<li class="blockList"> -<!-- =========== FIELD SUMMARY =========== --> -<ul class="blockList"> -<li class="blockList"><a name="field_summary"> -<!-- --> -</a> -<h3>Field Summary</h3> -<table class="overviewSummary" border="0" cellpadding="3" cellspacing="0" summary="Field Summary table, listing fields, and an explanation"> -<caption><span>Fields</span><span class="tabEnd"> </span></caption> -<tr> -<th class="colFirst" scope="col">Modifier and Type</th> -<th class="colLast" scope="col">Field and Description</th> -</tr> -<tr class="altColor"> -<td class="colFirst"><code>protected long</code></td> -<td class="colLast"><code><strong><a href="../../../org/libjpegturbo/turbojpeg/YUVImage.html#handle">handle</a></strong></code> </td> -</tr> -<tr class="rowColor"> -<td class="colFirst"><code>protected int</code></td> -<td class="colLast"><code><strong><a href="../../../org/libjpegturbo/turbojpeg/YUVImage.html#yuvHeight">yuvHeight</a></strong></code> </td> -</tr> -<tr class="altColor"> -<td class="colFirst"><code>protected int[]</code></td> -<td class="colLast"><code><strong><a href="../../../org/libjpegturbo/turbojpeg/YUVImage.html#yuvOffsets">yuvOffsets</a></strong></code> </td> -</tr> -<tr class="rowColor"> -<td class="colFirst"><code>protected int</code></td> -<td class="colLast"><code><strong><a href="../../../org/libjpegturbo/turbojpeg/YUVImage.html#yuvPad">yuvPad</a></strong></code> </td> -</tr> -<tr class="altColor"> -<td class="colFirst"><code>protected byte[][]</code></td> -<td class="colLast"><code><strong><a href="../../../org/libjpegturbo/turbojpeg/YUVImage.html#yuvPlanes">yuvPlanes</a></strong></code> </td> -</tr> -<tr class="rowColor"> -<td class="colFirst"><code>protected int[]</code></td> -<td class="colLast"><code><strong><a href="../../../org/libjpegturbo/turbojpeg/YUVImage.html#yuvStrides">yuvStrides</a></strong></code> </td> -</tr> -<tr class="altColor"> -<td class="colFirst"><code>protected int</code></td> -<td class="colLast"><code><strong><a href="../../../org/libjpegturbo/turbojpeg/YUVImage.html#yuvSubsamp">yuvSubsamp</a></strong></code> </td> -</tr> -<tr class="rowColor"> -<td class="colFirst"><code>protected int</code></td> -<td class="colLast"><code><strong><a href="../../../org/libjpegturbo/turbojpeg/YUVImage.html#yuvWidth">yuvWidth</a></strong></code> </td> -</tr> -</table> -</li> -</ul> -<!-- ======== CONSTRUCTOR SUMMARY ======== --> -<ul class="blockList"> -<li class="blockList"><a name="constructor_summary"> -<!-- --> -</a> -<h3>Constructor Summary</h3> -<table class="overviewSummary" border="0" cellpadding="3" cellspacing="0" summary="Constructor Summary table, listing constructors, and an explanation"> -<caption><span>Constructors</span><span class="tabEnd"> </span></caption> -<tr> -<th class="colOne" scope="col">Constructor and Description</th> -</tr> -<tr class="altColor"> -<td class="colOne"><code><strong><a href="../../../org/libjpegturbo/turbojpeg/YUVImage.html#YUVImage(byte[][],%20int[],%20int,%20int[],%20int,%20int)">YUVImage</a></strong>(byte[][] planes, -

On such systems, libjpeg-turbo is -generally 2-6x as fast as libjpeg, all else being equal. On other types of -systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by -virtue of its highly-optimized Huffman coding routines. In many cases, the -performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. - -libjpeg-turbo implements both the traditional libjpeg API as well as the less -powerful but more straightforward TurboJPEG API. libjpeg-turbo also features -colorspace extensions that allow it to compress from/decompress to 32-bit and -big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java -interface. - -libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated -derivative of libjpeg v6b developed by Miyasaka Masaru. The TigerVNC and -VirtualGL projects made numerous enhancements to the codec in 2009, and in -early 2010, libjpeg-turbo spun off into an independent project, with the goal -of making high-speed JPEG compression/decompression technology available to a -broader range of users and developers. - -#-->%prep -#-->%setup -q -n @CMAKE_PROJECT_NAME@-%{version} - -#-->%build -#-->cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=@CMAKE_BUILD_TYPE@ \ -#--> -DBUILD=%{release} \ -#--> -DCMAKE_INSTALL_BINDIR=%{_bindir} \ -#--> -DCMAKE_INSTALL_DATAROOTDIR=%{_datarootdir} \ -#--> -DCMAKE_INSTALL_DOCDIR=%{_docdir} \ -#--> -DCMAKE_INSTALL_INCLUDEDIR=%{_includedir} \ -#--> -DCMAKE_INSTALL_JAVADIR=%{_javadir} \ -#--> -DCMAKE_INSTALL_LIBDIR=%{_libdir} \ -#--> -DCMAKE_INSTALL_MANDIR=%{_mandir} \ -#--> -DCMAKE_INSTALL_PREFIX=%{_prefix} \ -#--> -DCMAKE_POSITION_INDEPENDENT_CODE=@CMAKE_POSITION_INDEPENDENT_CODE@ \ -#--> -DENABLE_SHARED=@ENABLE_SHARED@ -DENABLE_STATIC=@ENABLE_STATIC@ \ -#--> -DSO_MAJOR_VERSION=@SO_MAJOR_VERSION@ \ -#--> -DSO_MINOR_VERSION=@SO_MINOR_VERSION@ \ -#--> -DJPEG_LIB_VERSION=@JPEG_LIB_VERSION@ \ -#--> -DREQUIRE_SIMD=@REQUIRE_SIMD@ \ -#--> -DWITH_12BIT=@WITH_12BIT@ -DWITH_ARITH_DEC=@WITH_ARITH_DEC@ \ -#--> -DWITH_ARITH_ENC=@WITH_ARITH_ENC@ -DWITH_JAVA=@WITH_JAVA@ \ -#--> -DWITH_JPEG7=@WITH_JPEG7@ -DWITH_JPEG8=@WITH_JPEG8@ \ -#--> -DWITH_MEM_SRCDST=@WITH_MEM_SRCDST@ -DWITH_SIMD=@WITH_SIMD@ \ -#--> -DWITH_TURBOJPEG=@WITH_TURBOJPEG@ . -#-->make DESTDIR=$RPM_BUILD_ROOT - -%install - -rm -rf $RPM_BUILD_ROOT -make install DESTDIR=$RPM_BUILD_ROOT -/sbin/ldconfig -n $RPM_BUILD_ROOT%{_libdir} - -#-->%if 0 - -# This is only needed to support in-tree RPM generation via 'make rpm'.
