"Lieven Govaerts discovered that the Subversion mod_dav_svn module
incorrectly handled certain request methods when SVNListParentPath was
enabled. A remote attacker could use this issue to cause the server to
crash, resulting in a denial of service. This issue only affected
Ubuntu 12.04 LTS. (CVE-2014-0032)

Ben Reser discovered that Subversion did not correctly validate SSL
certificates containing wildcards. A remote attacker could exploit
this to perform a man in the middle attack to view sensitive
information or alter encrypted communications. (CVE-2014-3522)

Bert Huijben discovered that Subversion did not properly handle cached
credentials. A malicious server could possibly use this issue to
obtain credentials cached for a different server. (CVE-2014-3528).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
