Subject: [USN-538-1] libpng vulnerabilities

=========================================================== 
Ubuntu Security Notice USN-538-1           October 25, 2007
libpng vulnerabilities
CVE-2007-5268, CVE-2007-5269
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04
Ubuntu 7.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  libpng12-0                      1.2.8rel-5ubuntu0.3

Ubuntu 6.10:
  libpng12-0                      1.2.8rel-5.1ubuntu0.3

Ubuntu 7.04:
  libpng12-0                      1.2.15~beta5-1ubuntu1.1

Ubuntu 7.10:
  libpng12-0                      1.2.15~beta5-2ubuntu0.1

After a standard system upgrade you need to reboot your computer to
affect the necessary changes.

Details follow:

It was discovered that libpng did not properly perform bounds checking
and comparisons in certain operations. An attacker could send a specially
crafted PNG image and cause a denial of service in applications linked
against libpng.
