  script_tag(name:"insight", value:"Multiple flaws are due to:

  - Algorithmic complexity vulnerability in the 'multipart_buffer_headers'
    function in main/rfc1867.c script in PHP.

  - 'pcntl_exec' implementation in PHP truncates a pathname upon encountering a
    \x00 character.

  - Integer overflow in the 'ftp_genlist' function in ext/ftp/ftp.c script in PHP.

  - The 'phar_parse_tarfile' function in ext/phar/tar.c script in PHP does not
    verify that the first character of a filename is different from the
    \0 character.");
