CVE-2015-5695 — Openstack Designate security vulnerability

Medium CVSS 6.5

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.

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.
