RHEL 2.1 / 3 : libpng (RHSA-2004:180)

Medium Nessus Plugin ID 12492


The remote Red Hat host is missing one or more security updates.


Updated libpng packages that fix a out of bounds memory access are now available.

The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.

Steve Grubb discovered a out of bounds memory access flaw in libpng.
An attacker could carefully craft a PNG file in such a way that it would cause an application linked to libpng to crash when opened by a victim. This issue may not be used to execute arbitrary code.

Users are advised to upgrade to these updated packages that contain a backported security fix not vulnerable to this issue.


Update the affected packages.
