Mandriva Linux Security Advisory 2010-007 - The (1) htmlentities and (2) htmlspecialchars functions in PHP before 5.2.5 accept partial multibyte sequences, which has unknown impact and attack vectors, a different issue than CVE-2006-5465. The zend_restore_ini_entry_cb function in zend_ini.c in PHP 5.3.0, 5.2.10, and earlier versions allows context-specific attackers to obtain sensitive information (memory contents) and cause a PHP crash by using the ini_set function to declare a variable, then using the ini_restore function to restore the variable. The htmlspecialchars function in PHP before 5.2.12 does not properly handle (1) overlong UTF-8 sequences, (2) invalid Shift_JIS sequences, and (3) invalid EUC-JP sequences, which allows remote attackers to conduct cross-site scripting (XSS) attacks by placing a crafted byte sequence before a special character. The updated packages have been patched to correct these issues.

Package : php
Date : January 15, 2010
Affected: Multi Network Firewall 2.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been found and corrected in php:

The (1) htmlentities and (2) htmlspecialchars functions in PHP before
5.2.5 accept partial multibyte sequences, which has unknown impact and
attack vectors, a different issue than CVE-2006-5465 (CVE-2007-5898).

The zend_restore_ini_entry_cb function in zend_ini.c in PHP 5.3.0,
5.2.10, and earlier versions allows context-specific attackers to
obtain sensitive information (memory contents) and cause a PHP crash
by using the ini_set function to declare a variable, then using the
ini_restore function to restore the variable (CVE-2009-2626).

The htmlspecialchars function in PHP before 5.2.12 does not properly
handle (1) overlong UTF-8 sequences, (2) invalid Shift_JIS sequences,
and (3) invalid EUC-JP sequences, which allows remote attackers to
conduct cross-site scripting (XSS) attacks by placing a crafted byte
sequence before a special character (CVE-2009-4142).

The updated packages have been patched to correct these issues.
