=========================================================== 
Ubuntu Security Notice USN-500-1            August 20, 2007
rsync vulnerability
CVE-2007-4091
===========================================================

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:
  rsync                                    2.6.6-1ubuntu2.1

Ubuntu 6.10:
  rsync                                    2.6.8-2ubuntu3.1

Ubuntu 7.04:
  rsync                                    2.6.9-3ubuntu1.1

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

Details follow:

Sebastian Krahmer discovered that rsync contained an off-by-one
miscalculation when handling certain file paths.  By creating a specially
crafted tree of files and tricking an rsync server into processing them,
a remote attacker could write a single NULL to stack memory, possibly
leading to arbitrary code execution.
