libpng (PNG library) is a collection of routines used to create and manipulate PNG format graphics files. The PNG format was designed as a replacement for GIF and, to a lesser extent, TIFF, with many improvements and extensions. License: OSI Approved Changes:
This release fixes a newly discovered vulnerability in which some arrays of pointers are not initialized prior to using malloc to define the pointers. If the application runs out of memory while executing the allocation loop (which can be forced by malevolent input), libpng will jump to a cleanup process that attempts to free all of the pointers, including the undefined ones.
