CVE intelligence and bounded remediation

CVE-2018-3172 — Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: RPC)

Medium CVSS 5.3

Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: RPC). Supported versions that are affected are 10 and 11.4. Easily exploitable vulnerability allows unauthenticated attacker with network access via Portmap v3 to compromise Solaris. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Solaris. CVSS 3.0 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

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.
