It seems to be allergic to '+'. As a result, writing to ".gz" files was not working with Zlib 1.2.8. Note that "w+b" must be used in the normal case since the test suite fails otherwise!</li> </ul> </blockquote> <p>2017-12-22 Bob Friesenhahn <<a class="reference external" href="mailto:bfriesen%40simple.dallas.tx.us">bfriesen<span>@</span>simple<span>.</span>dallas<span>.</span>tx<span>.</span>us</a>></p> <blockquote> <ul class="simple"> <li>coders/png.c (ReadMNGImage): Fix SourceForge issue #535 "heap-buffer-overflow in ReadMNGImage". Problem was caused by accessing byte before testing that limit has been reached, rather than testing for limit before accessing the byte. This means that it could only ever read one past the buffer allocation size.</li> <li>coders/webp.c (WriteWEBPImage): Fix SourceForge issue #536 "stack-buffer-overflow in WriteWEBPImage". Due to a change to use WebPMemoryWriter as part of the EXIF and ICC profile support addition (enabled with libwebp 0.5.0), the progress indicator callback is now passed a pointer to a wrong structure. This is quite unfortunate since the progress indication is useful. The progress indication is temporarily disabled when the WebPMemoryWriter is in use until a solution is implemented. (ProgressCallback): Re-implement progress callback so that image pointer is stored/retrieved as thread-specific data.</li> <li>coders/png.c (ReadMNGImage): Fix SourceForge issue #537 "null pointer dereference in ReadMNGImage". DEFI chunk must be at least 2 bytes long.</li> <li>coders/tiff.c (ReadNewsProfile): Fix SourceForge issue #533 "heap-buffer-overflow on LocaleNCompare". LocaleNCompare() was being allowed to read heap data beyond the allocated region.</li> </ul> </blockquote> <p>2017-12-17 Bob Friesenhahn <<a class="reference external" href="mailto:bfriesen%40simple.dallas.tx.us">bfriesen<span>@</span>simple<span>.</span>dallas<span>.</span>tx<span>.</span>us</a>></p> <blockquote> <ul class="simple"> <li>magick/shear.c (IntegralRotateImage): Assure that reported error in rotate by 270 case does immediately terminate processing. Return a NULL Image pointer if there is a problem rather than a corrupted image. Fix is related to SourceForge issue #532 "heap-buffer-overflow bug in ReadWPGImage".</li> <li>magick/pixel_cache.c (AcquireCacheNexus): Add a check that the pixel cache is compatible with the image dimensions.
