(PHP: Memory disclosure and arbitrary location file upload)

    Stefano Di Paola discovered two bugs in PHP. The first is a parse error in
    php_variables.c that could allow a remote attacker to view the contents of
    the target machine's memory. Additionally, an array processing error in the
    SAPI_POST_HANDLER_FUNC() function inside rfc1867.c could lead to the
    $_FILES array being overwritten.
  
Impact :

    A remote attacker could exploit the first vulnerability to view memory
    contents. On a server with a script that provides file uploads, an attacker
    could exploit the second vulnerability to upload files to an arbitrary
    location. On systems where the HTTP server is allowed to write in a
    HTTP-accessible location, this could lead to remote execution of arbitrary
    commands with the rights of the HTTP server.
  
Workaround :

    There is no known workaround at this time."
