===========================================================
Ubuntu Security Notice USN-709-1           January 15, 2009
tar vulnerability
CVE-2007-4476
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
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:
  tar                             1.15.1-2ubuntu2.3

Ubuntu 7.10:
  tar                             1.18-2ubuntu1.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

Dmitry V. Levin discovered a buffer overflow in tar. If a user or automated
system were tricked into opening a specially crafted tar file, an attacker
could crash tar or possibly execute arbitrary code with the privileges of the
user invoking the program.
