CVE-2025-43970

GoBGP before 3.35.0 has an input length check flaw in pkg/packet/mrt/mrt.go during MRT parsing, where it fails to ensure required lengths (12 or 36 bytes depending on address family). The issue is documented in CVE-2025-43970 and is addressed by upgrading to GoBGP 3.35.0 or later. The Connected d...

CVE-2025-43971

CVE-2025-43971 affects GoBGP prior to 3.35.0. The flaw in pkg/packet/bgp/bgp.go allows a panic to be triggered by a zero value for softwareVersionLen, as described in the vulnerability note. The issue is limited to the GoBGP code path involving BGP packet handling, and the impact is a denial of s...

CVE-2025-43972

CVE-2025-43972 affects GoBGP prior to 3.35.0. The vulnerability is in the flowspec parser within pkg/packet/bgp/bgp.go, where an attacker can trigger a crash by sending fewer than 20 bytes in a specific context. The impact is a crash (potential denial via crash) as described in multiple sources. ...

CVE-2025-43973

GoBGP before 3.35.0 contains an input length check in pkg/packet/rtr/rtr.go that does not verify there are enough bytes to form an RTR message. This can lead to processing issues when handling RTR messages. The issue is fixed in or after GoBGP 3.35.0; affected components are the RTR message handl...
