Description Mark J. Cox (Product Security) 2003-01-06 06:01:59 EST
Unpatched versions of libpng 1.2.1 and earlier do not correctly calculate
offsets, which leads to a buffer overflow and the possibility of arbitrary
code execution.  This could be exploited by an attacker creating a
carefully crafted PNG file which could execute arbitrary code when the
victim views it.

Packages within Red Hat Linux, such as Mozilla, make use of the shared
libpng library. Therefore, all users are advised to upgrade to the errata
packages.

We're working on an erratum which will contain a backported fix for this issue
to libpng 1.0.14
