User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Ubuntu Robert Buchholz discovered that libsndfile did not correctly validate the size of its memory buffers. If a user were tricked into playing a specially crafted FLAC file, a remote attacker could execute arbitrary code with user privileges.
=========================================================== 
Ubuntu Security Notice USN-525-1           October 04, 2007
libsndfile vulnerability
CVE-2007-4974
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04

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:
  libsndfile1                     1.0.12-3ubuntu1

Ubuntu 6.10:
  libsndfile1                     1.0.16-1ubuntu0.6.10.1

Ubuntu 7.04:
  libsndfile1                     1.0.16-1ubuntu0.7.04.1

After a standard system upgrade you need to restart your session to affect
the necessary changes.

Details follow:

Robert Buchholz discovered that libsndfile did not correctly validate the
size of its memory buffers.  If a user were tricked into playing a specially
crafted FLAC file, a remote attacker could execute arbitrary code with user
privileges.
