Security related fixes:
This flaw is caused by loading data from external sources (file, custom ctx,
etc) and are hard to validate before calling libgd APIs:
- fix php bug 72339, Integer Overflow in _gd2GetHeader (CVE-2016-5766)
- bug #248, fix Out-Of-Bounds Read in read_image_tga
- gd: Buffer over-read issue when parsing crafted TGA file (CVE-2016-6132)
Using application provided parameters, in these cases invalid data causes
the issues:
- Integer overflow error within _gdContributionsAlloc() (CVE-2016-6207)
- fix php bug 72494, invalid color index not handled, can lead to crash ( CVE-2016-6128)
- improve color check for CropThreshold
The build system now enables -Wall and -Werror by default, so pass
--disable-werror to disable that. Notice that this issue has been fixed
upstream post-2.2.3:
