Name of the Vulnerable Software and Affected Versions FRRouting FRR version 9.0

Description An issue was discovered in FRRouting FRR, where the bgpd/bgp open.c file does not check for an overly large length of the rcv software version. This could allow a remote attacker to cause a denial of service.

Recommendations For FRRouting FRR version 9.0, as a temporary workaround, consider disabling the bgp open function in bgpd/bgp open.c until a patch is available. Restrict access to the bgpd module to minimize the risk of exploitation. Avoid using the rcv software version in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
