(PHP: Multiple vulnerabilities)

    Stefan Esser and Marcus Boerger reported several different issues in
    the unserialize() function, including serious exploitable bugs in the
    way it handles negative references (CAN-2004-1019).
    Stefan Esser also discovered that the pack() and unpack() functions are
    subject to integer overflows that can lead to a heap buffer overflow
    and a heap information leak. Finally, he found that the way
    multithreaded PHP handles safe_mode_exec_dir restrictions can be
    bypassed, and that various path truncation issues also allow to bypass
    path and safe_mode restrictions.
    Ilia Alshanetsky found a stack overflow issue in the exif_read_data()
    function (CAN-2004-1065). Finally, Daniel Fabian found that addslashes
    and magic_quotes_gpc do not properly escape null characters and that
    magic_quotes_gpc contains a bug that could lead to one level directory
    traversal.
  
Impact :

    These issues could be exploited by a remote attacker to retrieve web
    server heap information, bypass safe_mode or path restrictions and
    potentially execute arbitrary code with the rights of the web server
    running a PHP application.
  
Workaround :

    There is no known workaround at this time."
