Snort rule update for Jan. 14, 2021

Cisco Talos released the latest SNORTⓇ rule update this afternoon.

Thursday's release includes several rules to protect against the high-severity vulnerabilities Cisco disclosed in its RV series of routers. Cisco stated in its security advisory that it will not patch these products, but instead encouraged users to upgrade to more current hardware. However, these Snort rules will prevent attackers from carrying out a stack overflow attack.
