Test ID:1.3.6.1.4.1.25623.1.0.59189
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-500-1 (rsync)
Summary:Ubuntu USN-500-1 (rsync)
Description:
The remote host is missing an update to rsync
announced via advisory USN-500-1.

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.

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.

Solution:
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.
