The single patch released today addresses the much talked about IE 0-day, along with four other vulnerabilities. The 0-day (CVE-2012-4969) has already been exploited in the wild, so it is advisable to apply this patch as soon as possible. Keep in mind that Internet Explorer 6 through 9 are affected by this issue, so it is likely that all Windows systems in your environment are affected.

 

As always VERT recommends that you apply all the patches as soon as possible but also that you fully vet patches (when possible) before applying them to production systems.
