RedHat: RHSA-2015-0166:01 Moderate: subversion security update
Summary
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)
A NULL pointer dereference flaw was found in the way the mod_dav_svn module
handled certain requests for URIs that trigger a lookup of a virtual
transaction name. A remote, unauthenticated attacker could send a request
for a virtual transaction name that does not exist, causing mod_dav_svn to
crash. (CVE-2014-8108)
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 and CVE-2014-8108. 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.
Summary
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
