Description


Some 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 potentially compromise a vulnerable system.

1) An off-by-one error in the Certificate Trust List Provider service (CTLProvider.exe) can be exploited to cause a heap-based buffer overflow by sending specially crafted packets to the vulnerable service (default port 2444/TCP).

Note: This vulnerability does not affect CUCM 3.x.

2) An integer overflow error in the Real-Time Information Server (RIS) Data Collector service (RisDC.exe) can be exploited to cause a heap-based buffer overflow by sending specially crafted packets to the vulnerable service (default port 2556/TCP).

Successful exploitation may allow execution of arbitrary code.
