2023-03-17Fix bug in block type selection when Z_FIXED used.Mark Adler
A fixed block could be chosen when a stored block was smaller. Now the smaller of the two is always chosen.

2023-03-17Remove redundant check in gz_look().Mark Adler
2023-03-17Fix bug in deflateBound() for level 0 and memLevel 9.Mark Adler
memLevel 9 would cause deflateBound() to assume the use of fixed blocks, even if the compression level was 0, which forces stored blocks. That could result in a bound less than the size of the compressed data. Now level 0 always uses the stored blocks bound.
2023-03-17Fix crash when gzsetparams() attempted for transparent write.Mark Adler
gzsetparams() now returns a Z_STREAM_ERROR in this case.

inflateGetHeader(), and if multiple calls of inflate() delivered the extra header data, then there could be a buffer overflow of the provided space. This commit assures that provided space is not exceeded. See #1323.
2023-03-17cmake: respect custom `RC` flags and delete `GCC_WINDRES`Viktor Szakats
Before this patch, `zlib.rc` was compiled using a manual command [1] when using the MinGW (and MSYS/Cygwin) toolchains. This method ignores `CMAKE_RC_FLAGS` and offers no other way to pass a custom flag, breaking the build in cases where a custom `windres` option is required. E.g. `--target=` or `-I` on some platforms and configuration, in particular with `llvm-windres`. This patch deletes the special case for these toolchains and lets CMake compile the `.rc` file the default way used for all Windows targets. I'm not entirely sure why this special case was added back in 2011. The need to pass `-DGCC_WINDRES` is my suspect. We can resolve this much simpler by adding this line for the targets that require it: set(CMAKE_RC_FLAGS "${CMAKE_RC_FLAGS} -DGCC_WINDRES") But, the `.rc` line protected by `GCC_WINDRES`, these days work just fine with `windres`. Moreover, that protected line are oboslete flags from the 16-bit era, which for a long time have no effect, as documented here: <https://docs.microsoft.com/windows/win32/menurc/common-resource-attributes> So, this patch deletes `GCC_WINDRES` from the project entirely.

compatibility.
2023-03-17Extend GZIP conditionalTobias Stoeckmann
If gzip support has been disabled during compilation then also consider gzip relevant states as invalid in deflateStateCheck. Also the gzip state definitions can be removed. This change leads to failure in test/example, and I am not sure what the GZIP conditional is trying to achieve. All gzip related functions are still defined in zlib.h Alternative approach is to remove the GZIP define.
2023-03-17Handle invalid windowBits in init functionsTobias Stoeckmann
Negative windowBits arguments are eventually turned positive in deflateInit2_ and inflateInit2_ (more precisely in inflateReset2). Such values are used to indicate that raw deflate/inflate should be performed. If a user supplies INT32_MIN for windowBits, the code will perform -INT32_MIN which does not fit into int32_t. In fact, this is undefined behavior in C and should be avoided. Clearly this is a user error, but given the careful validation of input arguments a few lines later in deflateInit2_ I think this might be of interest. Proof of Concept: - Compile zlib-ng with gcc -ftrapv or -fsanitize=undefined - Compile and run this program: ``` #include <limits.h> #include <stdio.h> #include <zlib-ng.h> int main(void) { zng_stream de_stream = { 0 }, in_stream = { 0 }; int result; result = zng_deflateInit2(&de_stream, 0, Z_DEFLATED, INT32_MIN, MAX_MEM_LEVEL, Z_DEFAULT_STRATEGY); printf("zng_deflateInit2: %d\n", result); result = zng_inflateInit2(&in_stream, INT32_MIN); printf("zng_inflateInit2: %d\n", result); return 0; } ```
2023-03-17Add public compile definition for zlib-ng API so that other projects that ↵Nathan Moinvaziri
use CMake and link against the zlib project can easily determine whether or not to include "zlib-ng.h" or "zlib.h".
