Description:
Some vulnerabilities have been reported in Cisco Unified Communications Manager, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An error in the processing of SIP INVITE messages can be exploited to terminate a critical process and disrupt the voice services.
2) An error in the handling of network connections can be exploited to prevent new connections from being established to system services by establishing a high amount of TCP connections with an affected system.
3) Two errors in the processing of SIP and SCCP packets can be exploited to close the SIP port (5060/TCP and 5061/TCP) and SCCP port (2000/TCP and 2443/TCP) by flooding an affected system with TCP packets.
