Red Hat Security Advisory RHSA-2003:006-06 - Unpatched versions of libpng 1.2.1 and earlier do not correctly calculate offsets, which leads to a buffer overflow and arbitrary code execution. This can be exploited by an attacker creating a carefully crafted PNG file which executes arbitrary code when the victim views it.
