CHAT: Jabber 2.x Username Buffer Overflow

This signature detects attempts to overflow the username field in cleartext XMPP communications. Jabberd 2.x incorrectly verifies the username field length, enabling a malicious user to overflow a buffer. When Jabberd is running as root, an attacker can also execute arbitrary code.

Extended Description

Multiple remote buffer overflow vulnerabilities affect the Jabber Server. These issues are due to a failure of the application to properly validate the length of user-supplied strings prior to copying them into finite process buffers. An attacker may leverage these issues to execute arbitrary code on a computer with the privileges of the server process. This may facilitate unauthorized access or privilege escalation.
