Description:
Cisco has reported two vulnerabilities in the Cisco Firewall Services Module (FWSM) for Catalyst 6500 series and 7600 series, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerabilities are caused due to an unspecified error when processing SNMPv3 messages, and a boundary error when processing HTTP traffic requests for authentication using TACACS+ or RADIUS.
Successful exploitation of the vulnerabilities crashes and reloads a vulnerable device.
The vulnerabilities affect version 1.1.2 and prior.
Solution:
Update to version 1.1.3 or later.
See "Other References" section for a procedure to upgrade to a fixed software version.
Provided and/or discovered by:
