Debian DSA-531-1 : php4 - several vulnerabilities

medium Nessus Plugin ID 15368

Synopsis

The remote Debian host is missing a security-related update.

Description

Two vulnerabilities were discovered in php4 :

- CAN-2004-0594 The memory_limit functionality in PHP 4.x up to 4.3.7, and 5.x up to 5.0.0RC3, under certain conditions such as when register_globals is enabled, allows remote attackers to execute arbitrary code by triggering a memory_limit abort during execution of the zend_hash_init function and overwriting a HashTable destructor pointer before the initialization of key data structures is complete.

- CAN-2004-0595

The strip_tags function in PHP 4.x up to 4.3.7, and 5.x up to 5.0.0RC3, does not filter null (\0) characters within tag names when restricting input to allowed tags, which allows dangerous tags to be processed by web browsers such as Internet Explorer and Safari, which ignore null characters and facilitate the exploitation of cross-site scripting (XSS) vulnerabilities.

Solution

For the current stable distribution (woody), these problems have been fixed in version 4.1.2-7.

We recommend that you update your php4 package.
