CVE intelligence and bounded remediation
CVE-2022-3029 — Nlnetlabs Routinator security vulnerability
In NLnet Labs Routinator 0.9.0 up to and including 0.11.2, due to a mistake in error handling, data in RRDP snapshot and delta files that isn’t correctly base 64 encoded is treated as a fatal error and causes Routinator to exit. Worst case impact of this vulnerability is denial of service for the RPKI data that Routinator provides to routers. This may stop your network from validating route origins based on RPKI data. This vulnerability does not allow an attacker to manipulate RPKI data.

Matched remediation archetype
Resource exhaustion and denial of service
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
- Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
- Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.
Remediate safely
- Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
- Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
- Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
