"It was discovered that the mod_negotiation module incorrectly handled
certain filenames, which could result in browsers becoming vulnerable
to cross-site scripting attacks when processing the output. With
cross-site scripting vulnerabilities, if a user were tricked into
viewing server output during a crafted server request, a remote
attacker could exploit this to modify the contents, or steal
confidential data (such as passwords), within the same domain.
(CVE-2012-2687)

It was discovered that the Apache HTTP Server was vulnerable to the
'CRIME' SSL data compression attack. Although this issue had been
mitigated on the client with newer web browsers, this update also
disables SSL data compression on the server. A new SSLCompression
directive for Apache has been backported that may be used to re-enable
SSL data compression in certain environments. For more information,
please refer to:
http://httpd.apache.org/docs/2.4/mod/mod_ssl.html#sslcompression
(CVE-2012-4929).

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."
