"Stefano Di Paola discovered integer overflows in PHP's pack() and
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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
