Description:
Two vulnerabilities have been reported in the Cisco Catalyst Content Switching Modules (CSM) and Cisco Catalyst Content Switching Module with SSL (CSM-S), which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An unspecified error exists when processing certain TCP packets that were received out of order. This can be exploited to cause a high CPU load or a device reload due to a FPGA4 exception with icp.fatPath length error by sending specially crafted TCP packets to a vulnerable system.
2) An unspecified error exists within the "service termination" option, which can be exploited to cause a PGA4 exception 1 IDLE error under a high network load by sending specially crafted TCP packets to a vulnerable system.
Vulnerability #1 is reported in CSM 4.2 prior to 4.2.3a and CMS-S 2.1prior to 2.1.2a. Vulnerability #2 is reported in CSM 4.2 prior to 4.2.7 and CMS-S 2.1 prior to 2.1.6.
