"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."
