Adobe and Microsoft today each issued patches to fix critical security flaws in their software. Microsoft’s February Patch Tuesday includes seven patch bundles addressing at least 31 vulnerabilities in Windows and related software. Adobe pushed out an update that fixes two critical bugs in its Shockwave Player.
More than half of the updates issued by Microsoft today earned a “critical” rating — Microsoft’s most dire. That rating is assigned to vulnerabilities that can be exploited by malware or malcontents to take complete, remote control over vulnerable systems — with no help from users.
Microsoft is urging Windows users to apply all of the available fixes, but for those who need to prioritize patches (organizations that typically test patches before deploying them enterprise-wide), Redmond places a special focus on MS14-007, a graphics vulnerability in Windows 7/8/8.1 and Windows Server 2007, 2012 and Windows RT.
The cumulative, critical security update for all versions of Internet Explorer (MS14-010) fixes two dozen vulnerabilities, including one that Microsoft says has already been publicly disclosed. The other patch that Microsoft specifically called out — MS14-011 — addresses a vulnerability in VBScript that could cause problems for IE users.
Microsoft also once again is encouraging Windows users who haven’t already done so to consider installing and using its Enhanced Mitigation Experience Toolkit (EMET), a free tool that can help to significantly beef up the security of third-party applications that run on top of Windows. I would second their recommendation, and have reviewed EMET 4.0 here. The latest version — 4.1 — is available at this link and requires Microsoft’s .NET Framework 4 platform.
