CVE-2018-15769 — Dell Bsafe security vulnerability

High CVSS 7.5

RSA BSAFE Micro Edition Suite versions prior to 4.0.11 (in 4.0.x series) and versions prior to 4.1.6.2 (in 4.1.x series) contain a key management error issue. A malicious TLS server could potentially cause a Denial Of Service (DoS) on TLS clients during the handshake when a very large prime value is sent to the TLS client, and an Ephemeral or Anonymous Diffie-Hellman cipher suite (DHE or ADH) is used.

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.
