Description:
Cisco Unified CallManager (CUCM) is vulnerable to a buffer overflow, caused by improper bounds checking of hostnames within a Session Initiation Protocol (SIP) request. By sending a specially-crafted SIP request containing an overly long hostname, a remote attacker could overflow a buffer and execute arbitrary code or cause the affected device to crash.

- Cisco, Unified CallManager 5.0(1)
- Cisco, Unified CallManager 5.0(2)
- Cisco, Unified CallManager 5.0(3)
- Cisco, Unified CallManager 5.0(3A)
