"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)

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."
