Red Hat Security Advisory

Synopsis: Moderate: rsync security update
Advisory ID: RHSA-2011:0390-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0390.html
Issue date: 2011-03-28

================================================== ===================

1. Summary:

An updated rsync package that fixes one security issue is now available for
Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64

3. Description:

rsync is a program for synchronizing files over a network.

A memory corruption flaw was found in the way the rsync client processed
malformed file list data. If an rsync client used the "--recursive" and
"--delete" options without the "--owner" option when connecting to a
malicious rsync server, the malicious server could cause rsync on the
client system to crash or, possibly, execute arbitrary code with the
privileges of the user running rsync. (CVE-2011-1097)

Red Hat would like to thank Wayne Davison and Matt McCutchen for reporting
this issue.

Users of rsync should upgrade to this updated package, which contains a
backported patch to resolve this issue.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
