CVE-2018-1786 — IBM Spectrum Protect 7.1 and 8.1 dsmc and dsmcad processes incorrectly accumulate TCP/IP sockets in a CLOSE_WAIT state

High CVSS 7.5

IBM Spectrum Protect 7.1 and 8.1 dsmc and dsmcad processes incorrectly accumulate TCP/IP sockets in a CLOSE_WAIT state. This can cause TCP/IP resource leakage and may result in a denial of service. IBM X-Force ID: 148871.

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.
