- (PHP: Multiple security vulnerabilities)
-
-
- Several security vulnerabilities were found and fixed in version 4.3.8 of
- PHP. The strip_tags() function, used to sanitize user input, could in
- certain cases allow tags containing \\0 characters (CAN-2004-0595). When
- memory_limit is used, PHP might unsafely interrupt other functions
- (CAN-2004-0594). The ftok and itpc functions were missing safe_mode checks.
- It was possible to bypass open_basedir restrictions using MySQL\'s LOAD DATA
- LOCAL function. Furthermore, the IMAP extension was incorrectly allocating
- memory and alloca() calls were replaced with emalloc() for better stack
- protection.
-
- Impact
-
- Successfully exploited, the memory_limit problem could allow remote
- excution of arbitrary code. By exploiting the strip_tags vulnerability, it
- is possible to pass HTML code that would be considered as valid tags by the
- Microsoft Internet Explorer and Safari browsers. Using ftok, itpc or
- MySQL\'s LOAD DATA LOCAL, it is possible to bypass PHP configuration
- restrictions.
-
- Workaround
-
- There is no known workaround that would solve all these problems. All users
- are encouraged to upgrade to the latest available versions.

- Solution:
- All PHP, mod_php and php-cgi users should upgrade to the latest stable
- version:
- # emerge sync
- # emerge -pv ">=dev-php/php-4.3.8"
- # emerge ">=dev-php/php-4.3.8"
- # emerge -pv ">=dev-php/mod_php-4.3.8"
- # emerge ">=dev-php/mod_php-4.3.8"
- # emerge -pv ">=dev-php/php-cgi-4.3.8"
- # emerge ">=dev-php/php-cgi-4.3.8"
