What is CVE-2023-46753?

A vulnerability in FRRouting's handling of BGP UPDATE messages allows for potential crashes when crafted messages lacking mandatory attributes are processed. Specifically, a message with only an unknown transit attribute can disrupt normal operations, leading to a Denial of Service for affected versions of the software. Proper validation and error handling are essential to mitigate this issue and ensure the reliability of network routing operations.
