This month's Patch Tuesday has been a relative restrained affair with no critical fixes cropping up in Microsoft's slew of fixes for Windows, although nine out of the 13 vulnerabilities fixed in Internet Explorer were rated 'critical'.
Among them was a rather nasty scripting engine memory corruption vulnerability in the browser.
"The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user," said Microsoft's advisory.
"If the current user is logged on with administrative user rights, the attacker could take control of an affected system."
Microsoft's new Edge browser also had 13 security holes, 12 of which were rated 'critical', which have also been plugged.
Microsoft also patched a remote code execution vulnerability in Excel for Office 365, which could have enabled hackers to gain full control over a system if they'd managed to entice a victim to access a dodgy file or visit a nasty website that prompts a malicious download.
Both Windows 7 and Windows 8.1 had two vulnerabilities fixed by the software giant and Windows 10 in its five guises had three flaws apiece fixed.
Overall, some 34 security issues were scrubbed from Microsoft's software, but none of these had been disclosed to the public or were being actively exploited by hackers.
In fact the patch is so lacklustre that even Adobe merely rolled out a solitary patch for its Flash player, normally renowned to be full of holes that hackers can joyfully exploit.
So if you prefer to manually update Windows there's nothing in December's patch that should have you rushing to do so.
