Vulnerability from variot

Cisco CallManager (CCM) 3.2 and earlier, 3.3 before 3.3(5), 4.0 before 4.0(2a)SR2b, and 4.1 4.1 before 4.1(3)SR1 does not quickly time out Realtime Information Server Data Collection (RISDC) sockets, which results in a "resource leak" that allows remote attackers to cause a denial of service (memory and connection consumption) in RisDC.exe. This issue is documented in Cisco bug CSCed37403, which is available to Cisco customers. If attackers repeatedly create, and then drop TCP connections to the vulnerable service, excessive memory resources will be consumed, potentially leading to further connections being refused. This issue was originally documented in BID 14227. Cisco CallManager (CCM) is a set of call processing components based on the Cisco Unified Communications solution of Cisco. A denial of service vulnerability exists in multiple versions of CCM (3.2 and prior, 3.3 prior to 3.3(5), 4.0 prior to 4.0(2a)SR2b, and 4.1 prior to 4.1(3)SR1)

Cisco CallManager (CCM) is a set of call processing components based on the Cisco Unified Communications solution of Cisco. A denial of service vulnerability exists in multiple versions of CCM (3.2 and prior, 3.3 prior to 3.3(5), 4.0 prior to 4.0(2a)SR2b, and 4.1 prior to 4.1(3)SR1)",
