Description:
Some vulnerabilities have been reported in Cisco Unified CallManager (CUCM) and Cisco Unified Presence Server (CUPS), which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An unspecified error exists within the handling of large amounts of ICMP Echo packets. This can be exploited to crash various CUCM or CUPS services by sending a lot of ICMP Echo packets.
2) An unspecified error exists within the IPSec Manager service for CUCM or CUPS. This can be exploited to e.g. stop certain services like call forwarding by sending a specially crafted UDP packet to port 8500.
The vulnerabilities are reported in CUCM 5.0 versions prior to 5.0(4a)SU1, and CUPS 1.0 versions prior to 1.0(3).
