Red Hat Security Advisory
Synopsis: Moderate: subversion security and bug fix update
Advisory ID: RHSA-2011:0327-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0327.html
Issue date: 2011-03-08
CVE Names: CVE-2011-0715
=====================================================================
1. Summary:
Updated subversion packages that fix one security issue and one bug are now
available for Red Hat Enterprise Linux 5.
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:
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, 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 certain requests to lock working copy paths in a repository. A
remote attacker could issue a lock request that could cause the httpd
process serving the request to crash. (CVE-2011-0715)
Red Hat would like to thank Hyrum Wright of the Apache Subversion project
for reporting this issue. Upstream acknowledges Philip Martin, WANdisco,
Inc. as the original reporter.
This update also fixes the following bug:
* A regression was found in the handling of repositories which do not have
a "db/fsfs.conf" file. The "svnadmin hotcopy" command would fail when
trying to produce a copy of such a repository. This command has been fixed
to ignore the absence of the "fsfs.conf" file. The "svnadmin hotcopy"
command will now succeed for this type of repository. (BZ#681522)
All Subversion users should upgrade to these updated packages, which
contain backported patches to correct these issues. 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.
