===========================================================
Ubuntu Security Notice USN-257-1	  February 23, 2006
tar vulnerability
CVE-2006-0300
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

tar

The problem can be corrected by upgrading the affected package to
version 1.14-2ubuntu0.1 (for Ubuntu 5.04), or 1.15.1-2ubuntu0.1 (for
Ubuntu 5.10).  In general, a standard system upgrade is sufficient to
effect the necessary changes.

Details follow:

Jim Meyering discovered that tar did not properly verify the validity
of certain header fields in a GNU tar archive. By tricking an user
into processing a specially crafted tar archive, this could be
exploited to execute arbitrary code with the privileges of the user.

The tar version in Ubuntu 4.10 is not affected by this vulnerability.
