Security readout for executives and security teams
Plain-English summary
CVE-2018-11376 can crash radare2 2.5.0 when it processes a specially crafted ELF file. The business impact is disruption to reverse-engineering or malware-analysis workflows, not evidence of system takeover. Public sources do not provide CVSS scoring or broader affected-version detail.
Executive priority
Treat as a targeted operational stability risk for security tooling. Prioritize remediation where radare2 handles untrusted files, especially in automated analysis pipelines.
Technical view
The issue is a heap-based out-of-bounds read in radare2's r_read_le32() path, triggered during ELF parsing. The published impact is denial of service through application crash. The source bundle cites a GitHub issue and a corrective commit, but no named fixed release or CWE.
Likely exposure
Exposure is most likely in systems or analyst workstations running radare2 2.5.0 that inspect untrusted ELF files. Sources do not identify other products or versions.
Exploitation context
The CVE describes remote attackers causing a crash via a crafted ELF file. CISA KEV status is false, and the supplied sources do not establish active exploitation in the wild.
Researcher notes
Evidence is limited to the CVE description, GitHub issue, and commit reference. No CVSS, CWE, fixed release, or exploitation evidence is provided in the source bundle.
Mitigation direction
- Inventory environments using radare2, especially version 2.5.0.
- Update radare2 according to vendor guidance and the referenced corrective commit.
- Avoid processing untrusted ELF files with affected builds until remediated.
- Run radare2 in isolated analysis environments for untrusted samples.
Validation and detection
- Confirm whether radare2 2.5.0 is installed in analyst or automation environments.
- Check whether deployed builds include the referenced corrective commit.
- Review workflows that automatically process externally supplied ELF files.
- Verify remediation with controlled internal regression testing, not public exploit reproduction.
