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.
1) A boundary error in the Centralized TFTP File Locator Service of CUCM TFTP when processing filenames can be exploited to cause a buffer overflow.
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.

Update to the latest versions (see vendor's advisory).
