What is CVE-2024-31949?

FRRouting versions up to 9.1 are susceptible to an infinite loop condition triggered by malformed data received as a dynamic capability. Specifically, when the system processes MP/GR capabilities, if the incoming data is improperly formatted, it leads to a failure in pointer advancement. This results in an unresponsive state, potentially affecting network operations and services relying on FRRouting. It is crucial for users to review and apply the latest updates to mitigate this issue.
