Security readout for executives and security teams

Plain-English summary

CVE-2018-11384 is a crash vulnerability in radare2 2.5.0 when it processes a specially crafted ELF file. Business impact is mainly disruption to reverse-engineering, malware-analysis, or automated file-inspection workflows. The provided sources do not show code execution or confirmed active exploitation.

Executive priority

Treat this as a targeted operational-risk issue, not a broad enterprise emergency. Prioritize remediation where radare2 processes untrusted binaries automatically or supports security operations that cannot tolerate crashes.

Technical view

The issue is a heap-based out-of-bounds read in radare2's sh_op() function. A crafted ELF file can trigger an application crash, producing denial of service. Public references include a GitHub issue and commit, but the bundle does not provide CVSS, CWE, or a named fixed release.

Likely exposure

Exposure is most likely where radare2 2.5.0 analyzes untrusted ELF files, especially malware labs, triage sandboxes, CI pipelines, and reverse-engineering workstations. General enterprise exposure is limited unless radare2 is embedded in automated services.

Exploitation context

The source bundle describes remote attackers causing denial of service through a crafted ELF file. CISA KEV is false, and no cited source in the bundle confirms active exploitation in the wild.

Researcher notes

Evidence is sparse: the CVE description names radare2 2.5.0, sh_op(), crafted ELF input, heap out-of-bounds read, and crash. The bundle does not include CVSS, CWE, exploit maturity, or a specific fixed version.

Mitigation direction

  • Inventory systems and containers for radare2 2.5.0.
  • Upgrade radare2 to a vendor-fixed build when available.
  • Review the referenced upstream commit and issue for fix provenance.
  • Avoid processing untrusted ELF files with affected builds.
  • Isolate automated analysis workers that must handle untrusted samples.

Validation and detection

  • Confirm whether radare2 2.5.0 is installed or embedded.
  • Identify workflows that pass external ELF files to radare2.
  • Check whether the build includes commit 77c47cf873dd55b396da60baa2ca83bbd39e4add.
  • Verify vendor release notes before marking the issue remediated.
  • Review crash telemetry from analysis systems for related failures.
