CVE-2017-2313 — Juniper Junos security vulnerability

High CVSS 7.5

Juniper Networks devices running affected Junos OS versions may be impacted by the receipt of a crafted BGP UPDATE which can lead to an rpd (routing process daemon) crash and restart. Repeated crashes of the rpd daemon can result in an extended denial of service condition. The affected Junos OS versions are: 15.1 prior to 15.1F2-S15, 15.1F5-S7, 15.1F6-S5, 15.1F7, 15.1R4-S7, 15.1R5-S2, 15.1R6; 15.1X49 prior to 15.1X49-D78, 15.1X49-D80; 15.1X53 prior to 15.1X53-D230, 15.1X53-D63, 15.1X53-D70; 16.1 prior to 16.1R3-S3, 16.1R4; 16.2 prior to 16.2R1-S3, 16.2R2; Releases prior to Junos OS 15.1 are unaffected by this vulnerability. 17.1R1, 17.2R1, and all subsequent releases have a resolution for this vulnerability.

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.
