Description

libpng contains an overflow condition in pngpread.c. The issue is triggered as user-supplied input is not properly sanitized when handling PNG files. With a specially crafted PNG file containing a malformed data height value, a context-dependent attacker can cause a buffer overflow to cause a denial of service or potentially execute arbitrary code.
