Microsoft today pushed software updates to plug dozens of security holes in Windows and related products, including a vulnerability that is already being exploited in active attacks. Also, Apple has issued an emergency update to fix a flaw that’s reportedly been abused to install spyware on iOS products, and Google ‘s got a new version of Chrome that tackles two zero-day flaws. Finally, Adobe has released critical security updates for Acrobat , Reader and a slew of other software.
Four of the flaws fixed in this patch batch earned Microsoft’s most-dire “critical” rating, meaning they could be exploited by miscreants or malware to remotely compromise a Windows PC with little or no help from the user.
Top of the critical heap is CVE-2021-40444 , which affects the “MSHTML” component of Internet Explorer (IE) on Windows 10 and many Windows Server versions. In a security advisory last week , Microsoft warned attackers already are exploiting the flaw through Microsoft Office applications as well as IE.
The critical bug CVE-2021-36965 is interesting, as it involves a remote code execution flaw in “WLAN AutoConfig,” the component in Windows 10 and many Server versions that handles auto-connections to Wi-Fi networks. One mitigating factor here is that the attacker and target would have to be on the same network, although many systems are configured to auto-connect to Wi-Fi network names with which they have previously connected.
Allan Liska , senior security architect at Recorded Future , said a similar vulnerability — CVE-2021-28316 — was announced in April.
“CVE-2021-28316 was a security bypass vulnerability, not remote code execution, and it has never been reported as publicly exploited,” Liska said. “That being said, the ubiquity of systems deployed with WLAN AutoConfig enabled could make it an attractive target for exploitation.” Continue reading →
