Cisco Unified Communications Manager CTLProvider.exe buffer overflow
| voip-filename-overflow (31437) |  High Risk |
Description:
The Certificate Trust List (CTL) Provider service (CTLProvider.exe) of the Cisco Unified Communications Manager (CUCM), formerly Cisco CallManager, is vulnerable to a heap-based buffer overflow caused by an off-by-one error. By sending a specially-crafted packet containing a negative value, a remote attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system or cause the service to crash.
Platforms Affected:
- Cisco, Unified CallManager 3.3(5)SR2
- Cisco, Unified CallManager 4.1(3)SR4
- Cisco, Unified CallManager 4.2(3)SR1
- Cisco, Unified CallManager 5.0
