Description

Stefan Esser has reported some vulnerabilities in Zend Platform, which can be exploited by malicious people to cause a DoS (Denial of Service), disclose sensitive information, bypass certain security restrictions, and potentially compromise a vulnerable system.

1) A boundary error exists in the ZendSession Manager Daemon when handling sessions. This can be exploited to crash the daemon by sending an overly long or a zero-length session identifier.

2) A boundary error exists in the mod_cluster module when handling sessions. This can be exploited to crash the module by sending an overly long or a zero-length session identifier.

Successful exploitation may lead to arbitrary code execution.

3) An error exists in the ZendSession Manager when handling session files, which can be exploited to create or read arbitrary session files on an affected system with privileges of the daemon.

This can potentially be exploited to execute arbitrary PHP code on the server when running with PHP4 prior to 4.4.3 or PHP5 prior to 5.1.4.

The vulnerabilities have been reported in version 2.2.1. Other versions may also be affected.


Solution
Update to version 2.2.1a.
