PHP: Multiple security vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200407-13 (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 permit tags containing \0 characters (CVE-2004-0595). When memory_limit is used, PHP might unsafely interrupt other functions (CVE-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 permit 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.
