TITLE:
Cisco Unified Communications Manager Two Vulnerabilities

SECUNIA ADVISORY ID:
SA26043

VERIFY ADVISORY:
http://secunia.com/advisories/26043/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From local network

SOFTWARE:
Cisco Unified CallManager 5.x
http://secunia.com/product/12535/
Cisco Unified CallManager 4.x
http://secunia.com/product/12534/
Cisco Unified CallManager 3.x
http://secunia.com/product/2805/

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).
