PHP vulnerabilities



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)

Update instructions

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

Ubuntu 7.04
  • php5-xmlrpc - 5.2.1-0ubuntu1.4
  • libapache2-mod-php5 - 5.2.1-0ubuntu1.4
Ubuntu 6.10
  • php5-xmlrpc - 5.1.6-1ubuntu2.6
  • libapache2-mod-php5 - 5.1.6-1ubuntu2.6
Ubuntu 6.06
  • php5-xmlrpc - 5.1.2-1ubuntu3.9
  • libapache2-mod-php5 - 5.1.2-1ubuntu3.9

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