Trustwave Protections Deployed: MS11-083

November 15, 2011 1 minute read Robert Foggia

Last week, it was Microsoft's Patch Tuesday! For November, Microsoft released one "critical" bulletin, two "important," and one "moderate". The most critical, MS11-083 (CVE-2011-2013) which indicates a flaw in the TCP/IP implementation that possibly allows remote code execution by an attacker flooding a vulnerable OS with crafted UDP packets.

Trustwave Spiderlabs has investigated the MS11-083 threat and the team has implemented protections for our Intrusion Detection System (IDS) platforms. The deployed solution relies on detecting unusual ICMP traffic associated with this attack. Trustwave offers a variety of security products to protect against the latest threats and below is the coverage for MS11-083.
