Sourcefire VRT Certified Snort Rules Update for 01/17/2013

Just released: Sourcefire VRT Certified Snort Rules Update for 01/17/2013

We welcome the introduction of the newest rule release for today from the VRT. In this release we introduced 91 new rules and made modifications to 38 additional rules.

There were no changes made to the snort.conf in this release.

The VRT would like to thank Avery Tarasov for his work on the following SIDS:

The VRT would also like to thank Tavis Ormandy for his work in finding a potential security issue with rule 3:20275.

From our assessment this looks like the potential impact is a DoS, however, we've been unable to cause this in our testing. We've rolled the subscriber sets to registered so everyone can download the updates. Additionally, the rule is not enabled in default policies so the exposure is limited.

In VRT's rule release:
The Sourcefire VRT has added and modified multiple rules in the app-detect, blacklist, browser-ie, dns, dos, exploit-kit, file-flash, file-identify, file-multimedia, file-office, file-other, file-pdf, indicator-obfuscation, malware-cnc, misc, netbios, os-windows, policy-social and web-client rule sets to provide coverage for emerging threats from these technologies.
