Microsoft released a long list of updates for Microsoft software today. The most interesting appear to be those patching Internet Explorer and the kernel software vulnerabilities. In all, ten critical use-after-free vulnerabilities are patched in IE along with one important Information Disclosure vulnerability. Almost all of these vulnerabilities were reported by external security researchers working through HPs Zero Day Initiative. The others may not have been actively used by threat actors, but as always, it is very important for all Internet Explorer users to update these asap.”]
