Cisco Security Advisory – The Cisco Content Switching Module (CSM) and Cisco Content Switching Module with SSL (CSM-S) contain a memory leak vulnerability that can result in a denial of service condition. The vulnerability exists when the CSM or CSM-S is configured for layer 7 load balancing. An attacker can trigger this vulnerability when the CSM or CSM-S processes TCP segments with a specific combination of TCP flags while servers behind the CSM/CSM-S are overloaded and/or fail to accept a TCP connection.
