Microsoft’s final Patch Tuesday of the decade will see the Redmond giant fix a zero-day flaw in Internet Explorer (IE) 6 and 7.
In total Microsoft will be fixing six vulnerabilities in Windows, IE and Office. Three fixes are rated as critical and the rest a listed as important. One of the critical patches is for the zero-day flaw, which targeted unpatched versions of IE 6 and 7 with JavaScript enabled.
Matthew Walker, regional director UK & Ireland at security firm Lumension, said that this flaw will have the biggest impact on businesses. “It will affect all user machines across the entire organisation,” he said. “It is critical across Windows 7, Vista and XP, requires a restart and impacts all versions of Internet Explorer (6, 7 and 8). IT departments need to be prepared to quickly assess and patch all end user machines throughout their organisation.”
Microsoft’s last round of patches, released in November, was rumoured to have caused a ‘black screen of death’ on a number of computers, rendering them unusable.
Security firm Prevx initially suggested that Microsoft’s update caused the issue, but after further investigation it was revealed that malware was the most likely cause. Prevx has since apologised to Microsoft.
