  - A reachable assertion was found in Frrouting frr-bgpd 8.3.0 in the peek_for_as4_capability function.
    Attackers can maliciously construct BGP open packets and send them to BGP peers running frr-bgpd,     resulting in DoS. (CVE-2022-36440)

  - 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. (CVE-2022-40302)
