Microsoft released 13 bulletins today instead of 14, as announced in the Patch Tuesday announcement some days ago. In their final Patch Tuesday for the year, Microsoft addressed bugs in Windows, Internet Explorer, and Microsoft Office, while adding in a fix for DUQU in the bulletin MS11-087, which is also known as the DUQU zero-day remote code execution flaw. Attackers embedding specially crafted TrueType fonts in documents can exploit this vulnerability in the Windows kernel. MS11-087 was given a ‘Critical’ rating.
MS11-092 also deserves attention in this security bulletin as it affects Windows Media Player and also allows an attacker remote code execution if a user opens a specially crafted Microsoft Digital Video Recording (.dvr-ms) file. Microsoft also includes fixes for Active Directory, OLE and the Windows kernel.
To lean more about Microsoft support for the affected software, more details on the security bulletins for December can be found in their official bulletin summary. Users may also refer to our Trend Micro security advisory page.
Users of Deep Security and OfficeScan with Intrusion Defense Firewall (IDF) plug-in can also find updates to their products that will protect them from threats exploiting the vulnerabilities made public today, in advance of IT administrators being able to roll out these patches to their systems.
