Updated libpng packages that fix a out of bounds memory access are now available.
The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. Steve Grubb discovered a out of bounds memory access flaw in libpng. An attacker could carefully craft a PNG file in such a way that it would cause an application linked to libpng to crash when opened by a victim. This issue may not be used to execute arbitrary code. Users are advised to upgrade to these updated packages that contain a backported security fix not vulnerable to this issue.
