A flaw was found in Freetype. An integer overflow vulnerability exists when processing specially crafted OpenType variable fonts. A local attacker could exploit this by convincing a user to open a malicious font file, which may lead to an out-of-bounds read and potential information disclosure or denial of service.

A heap based buffer overflow flaw has been discovered in LibPNG. Prior to version 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification.
