One of the vulnerabilities that Microsoft addressed as part of the October 2020 Patch Tuesday is a critical bug in Windows’ TCP/IP driver that could lead to the remote execution of code.
Tracked as CVE-2020-16898, the issue is triggered when the TCP/IP stack doesn’t handle ICMPv6 Router Advertisement packets properly. An attacker could send specially crafted ICMPv6 Router Advertisement packets to a remote Windows machine to exploit the flaw and execute arbitrary code, Microsoft explains.
The tech company notes that Windows 10 and Windows Server are vulnerable to attacks and that there are no mitigations. However, one workaround is available.
A second issue in the TCP/IP driver, which is tracked as CVE-2020-16899, could be exploited to cause the target computer to stop responding. This flaw too can be exploited through crafted packets, but would not result in code execution, Microsoft says. The company rated the flaw as important.
SophosLabs’ security researchers have published a video to demonstrate how the first vulnerability (CVE-2020-16898) can be exploited to trigger a Blue Screen of Death (BSoD). They described it as a so-called “Ping of Death” vulnerability.
