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.
Solution:
Apply updated versions:
Vulnerability #1 is corrected in CUCM versions 4.1(3)SR5, 4.2(3)SR2, 4.3(1)SR1 and 5.1(2).
Vulnerability #2 is corrected in CUCM versions 3.3(5)SR2b, 4.1(3)SR5, 4.2(3)SR2, 4.3(1)SR1 and 5.1(2).
