| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | List of changes since previous release from 2018 is quite long: * Fix crc32.c to compile local functions only if used. * Check for cc masquerading as gcc or clang in configure. * Remove destructive aspects of make distclean. * Separate out address sanitizing from warnings in configure. * Eliminate use of ULL constants. * Add fallthrough comments for gcc. * Clean up minizip to reduce warnings for testing. * Fix unztell64() in minizip to work past 4GB. (Daniël Hörchner) * minizip warning fix if MAXU32 already defined. (gvollant) * Replace black/white with allow/block. (theresa-m) * Fix indentation in minizip's zip.c. * Improve portability of contrib/minizip. * Correct typo in blast.c. * Change macro name in inflate.c to avoid collision in VxWorks. * Clarify gz* function interfaces, referring to parameter names. * Fix error in comment on the polynomial representation of a byte. * Fix memory leak on error in gzlog.c. * Avoid adding empty gzip member after gzflush with Z_FINISH. * Explicitly note that the 32-bit check values are 32 bits. * Use ARM crc32 instructions if the ARM architecture has them. * Add use of the ARMv8 crc32 instructions when requested. * Correct comment in crc32.c. * Don't bother computing check value after successful inflateSync(). * Use atomic test and set, if available, for dynamic CRC tables. * Speed up software CRC-32 computation by a factor of 1.5 to 3. * Add crc32_combine_gen() and crc32_combine_op() for fast combines. * Add tables for crc32_combine(), to speed it up by a factor of 200. * Fix the zran.c example to work on a multiple-member gzip file. * Add gznorm.c example, which normalizes gzip files. * Show all the codes for the maximum tables size in enough.c. * Clarify that prefix codes are counted in enough.c. * Use inline function instead of macro for index in enough.c. * Clean up code style in enough.c, update version. * Use a macro for the printf format of big_t in enough.c. * Use a structure to make globals in enough.c evident. * Assure that the number of bits for deflatePrime() is valid. * Fix a bug that can crash deflate on some input when using Z_FIXED. * Correct the initialization requirements for deflateInit2(). * Emphasize the need to continue decompressing gzip members. * Add legal disclaimer to README. * Fix deflateEnd() to not report an error at start of raw deflate. * Remove old assembler code in which bugs have manifested. * Make the names in functions declarations identical to definitions. * Avoid an undefined behavior of memcpy() in _tr_stored_block(). * Avoid undefined behaviors of memcpy() in gz*printf(). * Avoid an undefined behavior of memcpy() in gzappend(). * Avoid the use of ptrdiff_t. * Handle case where inflateSync used when header never processed. * Don't compute check value for raw inflate if asked to validate. * Add address checking in clang to -w option of configure. * Return an error if the gzputs string length can't fit in an int. * Small speedup to inflate [psumbera]. * Update use of errno for newer Windows CE versions. * Avoid some conversion warnings in gzread.c and gzwrite.c. * Have Makefile return non-zero error code on test failure. * Avoid a conversion error in gzseek when off_t type too small. * Fix CLEAR_HASH macro to be usable as a single statement. * Fix bug when window full in deflate_stored(). * Limit hash table inserts after switch from stored deflate. * Permit a deflateParams() parameter change as soon as possible. * Cygwin does not have _wopen(), so do not create gzopen_w() there. Removed 006-fix-compressor-crash-on-certain-inputs.patch which was hotfix for CVE-2018-25032 and is now included in this release. This release is not available on @SF (yet?) so the sources are now pulled from GitHub. Fixes: CVE-2018-25032 Signed-off-by: Petr Štetiar <ynezz@true.cz>
* zlib: backport security fix for a reproducible crash in compressorPetr Štetiar2022-03-241-0/+343
| | | | | | | | | | | | | | Tavis has just reported, that he was recently trying to track down a reproducible crash in a compressor. Believe it or not, it really was a bug in zlib-1.2.11 when compressing (not decompressing!) certain inputs. Tavis has reported it upstream, but it turns out the issue has been public since 2018, but the patch never made it into a release. As far as he knows, nobody ever assigned it a CVE.

* tools: zlib: do not hardcode the install prefix in zlib.pcJo-Philipp Wich2018-05-241-0/+14
Our pkg-config wrapper relies on the ability to redefine the $prefix and $exec_prefix variables in order to construct proper search paths relative to the build environment. Patch the .pc file template to construct libdir, sharedlibdir and includedir relative to the ${prefix} variable so that it can be overridden as needed. This also fixes the libxml2/host build issue raised at https://github.com/openwrt/packages/issues/6073 - it was caused by libxml2's configure picking up a wrong host search path through zlib.pc, letting it include the wrong endian.h, causing spurious member redeclaration errors in system headers.
