                   Red Hat Security Advisory

Synopsis:          Moderate: subversion security update
Advisory ID:       RHSA-2011:0861-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2011-0861.html
Issue date:        2011-06-08
CVE Names:         CVE-2011-1752 
=====================================================================

1. Summary:

Updated subversion packages that fix one security issue are now available
for Red Hat Enterprise Linux 4.

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 AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Description:

Subversion (SVN) is a concurrent version control system which enables one
or more users to collaborate in developing and maintaining a hierarchy of
files and directories while keeping a history of all changes. The
mod_dav_svn module is used with the Apache HTTP Server to allow access to
Subversion repositories via HTTP.

A NULL pointer dereference flaw was found in the way the mod_dav_svn module
processed requests submitted against the URL of a baselined resource. A
malicious, remote user could use this flaw to cause the httpd process
serving the request to crash. (CVE-2011-1752)

Red Hat would like to thank the Apache Subversion project for reporting
this issue. Upstream acknowledges Joe Schaefer of the Apache Software
Foundation as the original reporter.

All Subversion users should upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
updated packages, you must restart the httpd daemon, if you are using
mod_dav_svn, for the update to take effect.

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

5. Bugs fixed (http://bugzilla.redhat.com/):

709111 - CVE-2011-1752 subversion (mod_dav_svn): DoS (crash) via request to deliver baselined WebDAV resources
