Seven security bulletins have been released to address these issues.

Exploitation of the patched vulnerability in Windows Media Player (BID 51292, CVE-2012-0003) is occurring in the wild on malicious websites for remote code execution. Attacks are currently not widespread.

Customers are advised to install all applicable updates as soon as possible.

Threatcon Level 1
ThreatCon Level 1
Low : Basic network posture
This condition applies when there is no discernible network incident activity and no malicious code activity with a moderate or severe risk rating. Under these conditions, only a routine security posture, designed to defeat normal network threats, is warranted. Automated systems and alerting mechanisms should be used.
Threatcon Level 1
ThreatCon Level 2
Medium : Increased alertness
This condition applies when knowledge or the expectation of attack activity is present, without specific events occurring or when malicious code reaches a moderate risk rating. Under this condition, a careful examination of vulnerable and exposed systems is appropriate, security applications should be updated with new signatures and/or rules as soon as they become available and careful monitoring of logs is recommended. Changes to the security infrastructure are not required.
Threatcon Level 1
ThreatCon Level 3
High : Known threat
This condition applies when an isolated threat to the computing infrastructure is currently underway or when malicious code reaches a severe risk rating. Under this condition, increased monitoring is necessary, security applications should be updated with new signatures and/or rules as soon as they become available and redeployment and reconfiguration of security systems is recommended. People should be able to maintain this posture for a few weeks at a time, as threats come and go.
Threatcon Level 1
ThreatCon Level 4
Extreme : Full alert
This condition applies when extreme global network incident activity is in progress. Implementation of measures in this Threat Condition for more than a short period probably will create hardship and affect the normal operations of network infrastructure.
