A PHP4 security update is available for Ubuntu Linux

==========================================================
Ubuntu Security Notice USN-99-1 March 18, 2005
php4 vulnerabilities
CAN-2004-1018, CAN-2004-1063, CAN-2004-1064
==========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

libapache2-mod-php4
php4-cgi

The problem can be corrected by upgrading the affected package to version 4:4.3.8-3ubuntu7.5. In general, a standard system upgrade is sufficient to effect the necessary changes.



Details follow:

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).
