Ubuntu 8.04 LTS / 10.04 LTS / 11.10 / 12.04 LTS / 12.10 : apache2 vulnerabilities (USN-1627-1)

Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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).

Solution :

Update the affected apache2.2-common package.

Risk factor :

Low / CVSS Base Score : 2.6
(CVSS2#AV:N/AC:H/Au:N/C:N/I:P/A:N)
CVSS Temporal Score : 2.3
(CVSS2#E:ND/RL:OF/RC:C)
