Ubuntu Security Notice USN-485-1 July 17, 2007
php5 vulnerabilities
CVE-2007-1864, CVE-2007-2728

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
libapache2-mod-php5 5.1.2-1ubuntu3.9
php5-xmlrpc 5.1.2-1ubuntu3.9

Ubuntu 6.10:
libapache2-mod-php5 5.1.6-1ubuntu2.6
php5-xmlrpc 5.1.6-1ubuntu2.6

Ubuntu 7.04:
libapache2-mod-php5 5.2.1-0ubuntu1.4
php5-xmlrpc 5.2.1-0ubuntu1.4

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

It was discovered that the PHP xmlrpc extension did not correctly check
heap memory allocation sizes. A remote attacker could send a specially
crafted request to a PHP application using xmlrpc and execute arbitrary
code as the Apache user. (CVE-2007-1864)

Stefan Esser discovered a flaw in the random number initialization of the
PHP SOAP extension. This could lead to remote attackers being able to
predict certain elements of the authentication mechanism. (CVE-2007-2728)
