Red Hat Security Advisory

Synopsis: Moderate: subversion security update
Advisory ID: RHSA-2015:0165-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-0165.html
Issue date: 2015-02-10
CVE Names: CVE-2014-3528 CVE-2014-3580
=====================================================================

1. Summary:

Updated subversion packages that fix two security issues are now available
for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, noarch, 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
handled REPORT requests. A remote, unauthenticated attacker could use a
specially crafted REPORT request to crash mod_dav_svn. (CVE-2014-3580)

It was discovered that Subversion clients retrieved cached authentication
credentials using the MD5 hash of the server realm string without also
checking the server's URL. A malicious server able to provide a realm that
triggers an MD5 collision could possibly use this flaw to obtain the
credentials for a different realm. (CVE-2014-3528)

Red Hat would like to thank the Subversion project for reporting
CVE-2014-3580. Upstream acknowledges Evgeny Kotkov of VisualSVN as the
original reporter.

All subversion users should upgrade to these updated packages, which
contain backported patches to correct these issues. After installing the
updated packages, for the update to take effect, you must restart the httpd
daemon, if you are using mod_dav_svn, and the svnserve daemon, if you are
serving Subversion repositories via the svn:// protocol.

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/articles/11258

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

1125799 - CVE-2014-3528 subversion: credentials leak via MD5 collision
1174054 - CVE-2014-3580 subversion: NULL pointer dereference flaw in
mod_dav_svn when handling REPORT requests
