Doc Text:
A security issue was discovered in FRRouting (FRR). It is possible for an attacker to send excessive Resource Public Key Infrastructure (RPKI) updates, triggering FRR to re-validate all routes in the routing information base each time. This can cause high CPU and network bandwidth consumption, potentially leading to a denial of service.

Description OSIDB Bzimport 2025-01-06 23:01:12 UTC
