Description


Two vulnerabilities have been reported in Cisco Unified Communications Manager (CUCM), which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.

Successful exploitation may allow execution of arbitrary code.

2) An error when processing SIP INVITE messages can be exploited to cause a resource exhaustion by e.g. flooding a CUCM system with SIP INVITE messages to default port 5060/UDP.

Please see the vendor's advisory for a list of affected versions.
