Subject: [USN-600-1] rsync vulnerability

=========================================================== 
Ubuntu Security Notice USN-600-1             April 11, 2008
rsync vulnerability
CVE-2008-1720
===========================================================

A security issue affects the following Ubuntu releases:

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 7.04:
  rsync                           2.6.9-3ubuntu1.2

Ubuntu 7.10:
  rsync                           2.6.9-5ubuntu1.1

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

Details follow:

Sebastian Krahmer discovered that rsync could overflow when handling ACLs.
An attacker could construct a malicious set of files that when processed
by rsync could lead to arbitrary code execution or a crash.
