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. NOTE: this behavior occurs in bgp_open_option_parse in the bgp_open.c file, a different location (with a different attack vector) relative to CVE-2022-40302."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/FRRouting/frr/releases"},{"name":"DSA-5495","tags":["vendor-advisory"],"url":"https://www.debian.org/security/2023/dsa-5495"},{"name":"[debian-lts-announce] 20230919 [SECURITY] [DLA 3573-1] frr security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2023/09/msg00020.html"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T12:14:40.214Z"},"title":"CVE Program Container","references":[{"url":"https://github.com/FRRouting/frr/releases","tags":["x_transferred"]},{"name":"DSA-5495","tags":["vendor-advisory","x_transferred"],"url":"https://www.debian.org/security/2023/dsa-5495"},{"name":"[debian-lts-announce] 20230919 [SECURITY] [DLA 3573-1] frr security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2023/09/msg00020.html"}]}]}}
