Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Maksymilian Arciemowicz discovered that PHP did not properly handle
the ini_restore function. An attacker could exploit this issue to
obtain random memory contents or to cause the PHP server to crash,
resulting in a denial of service. (CVE-2009-2626)

It was discovered that the htmlspecialchars function did not properly
handle certain character sequences, 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-2009-4142)

Stefan Esser discovered that PHP did not properly handle session data.
An attacker could exploit this issue to bypass safe_mode or
open_basedir restrictions. (CVE-2009-4143).

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
