Description Alexander Bergmann 2023-05-04 06:12:40 UTC 
CVE-2022-40302

An issue was discovered in bgpd in FRRouting (FRR) through 8.4. By crafting a
BGP OPEN message with an option of type 0xff (Extended Length from RFC 9072),
attackers may cause a denial of service (assertion failure and daemon restart,
or out-of-bounds read). This is possible because of inconsistent boundary checks
that do not account for reading 3 bytes (instead of 2) in this 0xff case.
