CVE-2018-10850 — Fedoraproject 389 Directory Server security vulnerability

High CVSS 7.1

389-ds-base before versions 1.4.0.10, 1.3.8.3 is vulnerable to a race condition in the way 389-ds-base handles persistent search, resulting in a crash if the server is under load. An anonymous attacker could use this flaw to trigger a denial of service.

Race condition, TOCTOU, and lifecycle synchronization

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map concurrent actors, shared state, lock boundaries, signals, callbacks, retries, and check-then-use sequences in the affected path.
  • Determine whether untrusted users can influence timing, object names, filesystem state, or repeated state transitions.
  • Identify clustered and multi-process behavior that repository-local tests may not represent.

Remediate safely

  • Make the sensitive state transition atomic or protect it with a consistently ordered synchronization primitive.
  • Perform authorization and invariant checks on the same authoritative object and transaction used for the operation.
  • Use unique private resources, safe ownership transfer, and idempotent operations; add deterministic concurrency regression tests.
