This month's Patch Tuesday, unlike October's, is a quiet one, with just two security bulletins:
MS08-069 solves a remote code execution vulnerability in Microsoft's XML Core Service that is rated as Critical for version 3.0 and Important for later versions. All 32-bit and 64-bit desktop versions of Windows from Windows 2000 SP4 through Windows Vista SP1 are affected, as well as Microsoft Office 2003 and 2007. The Exploitability Index is 1 (Consistent Exploit Code Likely - the most serious ranking) or 2 (Inconsistent Exploit Code Likely), depending upon the version of XML Core Services installed. Windows Server 2003 and some installations of Windows Server 2008 are also affected.
MS08-068 patches a remote code execution vulnerability in the SMB protocol. MS08-068 is rated as Important for Windows 2000 SP4 and Windows XP, and Moderate for Windows Vista. Windows Server 2003 and all Windows Server 2008 installations are also affected. Despite Microsoft's rating this vulnerability as only Important rather than Critical, MS08-068's Exploitability Index is 1 because exploit code targeting Windows XP is already public.
That's it for Patch Tuesday security bulletins, both of which will be arriving soon via Windows Update (or can be downloaded manually if you prefer). What else has Microsoft served up?
The only non-security content this time is the usual monthly update for the Malicious Software Removal Tool (KB890830; not yet updated as this article was posted now updated) and the usual monthly update for the Windows Mail junk mail filter (KB905866), available in 32-bit and 64-bit versions.
