Mandriva Linux Security Advisory MDKSA-2007:087
http://www.mandriva.com/security/
_______________________________________________________________________

Package : php
Date : April 18, 2007
Affected: Corporate 3.0, Multi Network Firewall 2.0
_______________________________________________________________________

Problem Description:

A heap-based buffer overflow vulnerability was found in PHP's gd
extension. A script that could be forced to process WBMP images
from an untrusted source could result in arbitrary code execution
(CVE-2007-1001).

A DoS flaw was found in how PHP processed a deeply nested array.
A remote attacker could cause the PHP intrerpreter to creash
by submitting an input variable with a deeply nested array
(CVE-2007-1285).

A vulnerability was discovered in the way PHP's unserialize() function
processed data. A remote attacker able to pass arbitrary data to
PHP's unserialize() function could possibly execute arbitrary code
as the apache user (CVE-2007-1286).

A double-free flaw was found in the session_decode() function that
could allow a remote attacker to potentially execute arbitrary code
as the apache user if they are able to pass arbitrary data to PHP's
session_decode() function (CVE-2007-1711).

A vulnerability in how PHP's mail() function processed header data was
discovered. If a script sent mail using a subject header containing
a string from an untrusted source, a remote attacker could send bulk
email to unintended recipients (CVE-2007-1718).

Updated packages have been patched to correct these issues.
