Overview

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.

Mandriva Linux Security Advisory 2010-008

Mandriva Linux Security Advisory 2010-008 - 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. Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers. The updated packages have been patched to correct these issues.

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.

Ubuntu Security Notice 882-1
Posted Jan 14, 2010
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 882-1 - 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. 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.
