Description

Designate 2015.1.0 through 1.0.0.0b1 as packaged in OpenStack Kilo does not enforce RecordSets per domain, and Records per RecordSet quotas when processing an internal zone file transfer, which might allow remote attackers to cause a denial of service (infinite loop) via a crafted resource record set.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for designate, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of designate for CVE-2015-5695. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
