The fragments are reassembled by the receiving host. The reassembly limit controls the IP fragmentation, which is an Internet Protocol (IP) process that breaks packets into smaller fragments, so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size.

CVE-2021-24094 an IPv6 security vulnerability concerning the reassembly limit and related to the previous one.

Microsoft adds to say: IPv4 Source routing is considered insecure and is blocked by default in Windows however, a system will process the request and return an ICMP message denying the request.

CVE-2021-24074 an IPv4 security vulnerability concerning source routing behavior.

This is the only critical bug Microsoft listed as publicly known.

A remote code execution (RCE) attack happens when a threat actor illegally accesses and manipulates a computer or server without authorization from its owner. NET Core Remote Code Execution (RCE) vulnerability. For example, if an attacker gains access to a system but only has read-only permissions they can use an EoP vulnerability to raise them to “read and write”, giving them an option to make unwanted changes. With a EoP vulnerability attackers can raise their authorization permissions beyond those initially granted. This one we listed first as it’s actively exploited in the wild.

CVE-2021-1732 Windows Win32k elevation of privilege (EoP) vulnerability.

The most notable CVE’s in this update were: Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. Since there were no less than 56 patches in this month’s issue we will focus on the most important ones. This is the day when they roll out all the available patches for their software, and their operating systems in particular. Traditionally the second Tuesday of the month is Microsoft’s “patch Tuesday”.
