Cisco and Adobe also joined the parade, shipping updates for a slew of vulnerabilities that could cause denial-of-service, security bypass and cross-site scripting attacks.
Cisco's advisory, rated "moderately critical" by Secunia, contains patches for two separate vulnerabilities in Cisco IOS that could be exploit to bypass certain security restrictions.
The more serious of the two could cause Cisco IOS IPS signatures using regular expressions to mistakenly identify malicious traffic within fragmented IP packets. The second bug is an error within the ATOMIC.TCP scanning mechanism and signatures that could be exploited to crash a device by producing maliciously rigged network traffic.
All three Adobe issues could put users at risk of cross-site scripting attacks. Adobe rates the risks as "important" and "moderate."
[UPDATE: February 14, 2007, 4:44 PM] Since the publication of this entry, Cisco has issued two more security alerts, confirming multiple vulnerabilities in the Cisco Firewall Services Module (FWSM) and the Cisco PIX and ASA appliances. Patches for these are available here and here.
