Microsoft Patches Zero-Day Bug & 15 Other Flaws

Microsoft today issued a security patch to fix a zero-day vulnerability in Windows that hackers have been exploiting to break into vulnerable systems. The company also addressed at least 15 other flaws in its software, and urged customers to quit using the desktop Sidebar and Gadget capabilities offered in Windows 7 and Windows Vista.

By far the most urgent of the updates is MS12-043, which fixes a critical vulnerability in Microsoft XML Core Services that miscreants and malware alike have been using to break into vulnerable systems. Microsoft had already warned about limited, targeted attacks using this flaw, but late last month an exploit built to attack the XML bug was added to the BlackHole Exploit Kit, an automated browser exploit tool that is very popular in the criminal underground right now.

Other critical patch bundles include a fix for a dangerous flaw in the Microsoft Data Access Components (MDAC) of Windows, and an update to address a pair of vulnerabilities in Internet Explorer. Continue reading →

Microsoft Patches 26 Flaws, Warns of Zero-Day Attack

Microsoft today released updates to plug at least 26 separate security holes in its Windows operating systems and related software. At the same time, Microsoft has issued a stopgap fix for a newly-discovered flaw that attackers are actively exploiting.

The security fixes are included in seven security patch bundles, three of which earned Microsoft’s most dire “critical” label, signifying that attackers can exploit them without any help on the part of the user.  Redmond patched vulnerabilities in Windows, Internet Explorer, Dynamics AX, Microsoft Lync (Microsoft’s enterprise instant message software), and the Microsoft .NET Framework.

Microsoft called out two patches as particularly important: the Internet Explorer bundle (MS12-037), which addresses 13 issues; and a critical flaw in the Windows remote desktop protocol (RDP). Updates are available for all supported versions of Windows, via Windows Update or Automatic Update. Continue reading →
