USN-485-1: PHP vulnerabilities

Releases

• Ubuntu 7.04
• Ubuntu 6.10
• Ubuntu 6.06

Details

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)
