Multiple Security Vulnerabilities in PHP Announced

secunia.com released an advisory today on 11 security vulnerabilities in PHP versions prior to PHP 5.2.2.

1. An unspecified error in the “ftp_putcmd()” function can be exploited to inject newline characters.
2. An unspecified error in the “import_request_variables()” can be exploited to overwrite global variables.
3. An unspecified error can remotely be exploited to cause a buffer overflow within in the “make_http_soap_request()” function (PHP 5).
4. An unspecified error can be exploited to cause a buffer overflow within the “user_filter_factory_create()” function (PHP 5).
5. An unspecified error in the bundled libxmlrpc library can remotely be exploited to cause a buffer overflow.
6. An input validation error in the “mail()” function allows injection of headers via the “To” and “Subject” parameters.
7. An error in the “mail()” function allows to truncate messages via ASCIIZ bytes.
8. The “safe_mode” and “open_basedir” protection mechanisms can be bypassed via the “zip://” and “bzip://” wrappers.
9. An integer overflow exists in “substr_compare()”, which can be exploited to read memory from memory behind PHP variables. The “substr_count” function is reportedly also affected.
10. An error in the “mb_parse_str()” can be exploited to activate “register_globals”.
11. An error in the Zend engine related to nested array variables that can be exploited to crash a PHP application.

Their recommended solution:
Update to version 5.2.2 or 4.4.7. Grant only trusted users permission to execute PHP code.
