Microsoft has released a pair of Internet Explorer updates aimed at resolving a security vulnerability related to digital certificates – in the right situation, an attacker could use it to enable a number of identity spoofing attacks. The updates – version 5.1.6 for Mac OS 9 and 5.2.2 for Mac OS X – also include all the previous fixes. Microsoft didn’t make any release notes available, but it’s unlikely at the new versions incorporate any new features. Microsoft didn’t even update Internet Explorer’s installer in the Mac OS X version, which unnecessarily insists on quitting all active applications. Version 5.1.6 is a 5.4 MB download; version 5.2.2 is a 7.2 MB download.
