Update now! Microsoft and Adobe’s December 2018 Patch Tuesday is here


If you find patching security flaws strangely satisfying, you’re in luck – Microsoft’s and Adobe’s December Patch Tuesdays have arrived with plenty for the dedicated updater to get stuck into.

Don’t be fooled by the lighter-than-usual Windows patching load, featuring 39 CVE-level vulnerabilities, including nine rated critical.

Buried within these is a dangerous zero-day local privilege escalation flaw across all Windows versions, CVE-2018-8611, reportedly exploited by an APT group since at least October.

A second in the public domain but not yet known to be exploited is CVE-2018-8517, a .NET denial of service flaw. Both are rated ‘important’, probably because exploiting them depends on other compromises being deployed first.

As for the criticals, watch out for two remote code execution browser vulnerabilities in IE and Edge (CVE-2018-8631) and CVE-2018-8624 respectively), which Microsoft rates as exploit candidates – the same goes for CVE-2018-8628 in PowerPoint.
