CVE intelligence and bounded remediation

CVE-2017-14796 — Libbpg Project Libbpg security vulnerability

High CVSS 8.8

The hevc_write_frame function in libbpg.c in libbpg 0.9.7 allows remote attackers to cause a denial of service (integer underflow and application crash) or possibly have unspecified other impact via a crafted BPG file, related to improper interaction with copy_CTB_to_hv in hevc_filter.c in libavcodec in FFmpeg and sao_filter_CTB in hevc_filter.c in libavcodec in FFmpeg.

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.
