MS quashes infamous Bofra bug

IFRAME fix

Microsoft broke with its normal patching schedule yesterday to issue a fix for the notorious IFRAME vulnerability in Internet Explorer.

Windows XP SP2 users were immune to the vulnerability, which was exploited by the Bofra worm. Surfers using Mozilla Firefox and Opera browsers were not affected. But users of older versions of IE were left in the firing line from 2 November, when the vulnerability was discovered, until Microsoft’s cumulative patch yesterday.

Microsoft describes its fix for the IFRAME (AKA HTML Elements) vulnerability as critical. Users of IE 6.0 on Windows XP SP1, Windows 2000 (SP3 and SP4) and Windows NT4 are strongly urged to apply Microsoft’s cumulative patch. Microsoft's advisory is here.

Redmond's next scheduled monthly patch update is Tuesday, 7 December. ®
