Description
This security bulletin contains information about 1 security vulnerability.
1) Buffer access with incorrect length value (CVE-ID: CVE-2025-30651)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to buffer access with incorrect length value error in the routing protocol daemon (rpd). A remote non-authenticated attacker can cause a Denial of Service (DoS).

Continued receipt of this packet will cause a sustained DoS condition.
