Description

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 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.
