Scientific Linux Security Update : libpng on SL4.x i386/x86_64

medium Nessus Plugin ID 61099

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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

An uninitialized memory read issue was found in the way libpng processed certain PNG images that use the Physical Scale (sCAL) extension. An attacker could create a specially crafted PNG image that, when opened, could cause an application using libpng to crash.
(CVE-2011-2692)

Users of libpng and libpng10 should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using libpng or libpng10 must be restarted for the update to take effect.

Solution

Update the affected packages.
