unpack() functions. A malicious PHP script could exploit these to
break out of safe mode and execute arbitrary code with the privileges
of the PHP interpreter. (CAN-2004-1018)

Note: The second part of CAN-2004-1018 (buffer overflow in the
shmop_write() function) was already fixed in USN-66-1.

Stefan Esser discovered two safe mode bypasses which allowed malicious
PHP scripts to circumvent path restrictions. This was possible by
either using virtual_popen() with a current directory containing shell
metacharacters (CAN-2004-1063) or creating a specially crafted
directory whose length exceeded the capacity of the realpath()
function (CAN-2004-1064).");
