Emergency Fix for Windows Anti-Malware Flaw Leads May’s Patch Tuesday
Adobe and Microsoft both issued updates today to fix critical security vulnerabilities in their software. Microsoft actually issued an emergency update on Monday just hours ahead of today’s regularly scheduled “Patch Tuesday” (the 2nd Tuesday of each month) to fix a dangerous flaw present in most of Microsoft’s anti-malware technology that’s being called the worst Windows bug in recent memory. Separately, Adobe has a new version of its Flash Player software available that squashes at least seven nasty bugs.
Last week, Google security researcher Tavis Ormandy reported to Microsoft a flaw in its Malware Protection Engine, a technology that exists in most of Redmond’s malware protection offerings — including Microsoft Forefront, Microsoft Security Essentials and Windows Defender. Rather than worry about their malicious software making it past Microsoft’s anti-malware technology, attackers could simply exploit this flaw to run their malware automatically once their suspicious file is scanned.
