Summary
Fix CVE(s): CVE-2024-38286
Details
  • SECURITY UPDATE: Denial of Service caused by unbounded TLS handshake wrap queue in SecureNio2Channel / SecureNioChannel. Backport upstream fix from 9.0.x commit 76c5cce6f0bcef14b0c21c38910371ca7d322d13.
    • debian/patches/CVE-2024-38286.patch: cap the handshake wrap queue at HANDSHAKEWRAPQUEUELENGTHLIMIT (100) and close the connection with a localised error message if the cap is exceeded, covering both Nio2 and Nio connector variants. Also includes upstream follow-up bfa5de95ad ("Avoid possible lost update") which converts the SecureNio2Channel counter to AtomicInteger and resets it in reset() to prevent a non-atomic read-modify-write race.
    • CVE-2024-38286
