Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : php5 vulnerabilities (USN-882-1)

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.

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
CVSS Temporal Score : 7.4
