sipXtapi CSeq Field Header Denial of Service Vulnerability

Vulnerability Assessment Summary
Sends an SIP packet with a bad CSeq field

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote host contains an application that is vulnerable to a remote
buffer overflow attack.

Description :

The remote host is running a SIP user agent that appears to be
compiled using a version of SIP Foundry's SipXtapi library before
March 24, 2006. Such versions contain a buffer overflow flaw that is
triggered when processing a specially-crafted packet with a long value
for the 'CSeq' field. A remote attacker may be able to exploit this
issue to execute arbitrary code on the affected host subject to the
rights of the current user.
