Security readout for executives and security teams
Plain-English summary
CVE-2017-7716 is a crash bug in radare2 1.3.0 when processing a crafted WebAssembly file. The likely business impact is disruption to analysts or automated file-analysis pipelines, not confirmed data theft or system takeover based on the provided sources.
Executive priority
Treat this as a targeted availability risk for reverse-engineering and malware-analysis workflows. Prioritize if radare2 is used in automated intake pipelines or by security teams handling untrusted WebAssembly files.
Technical view
The issue is in radare2's read_u32_leb128 function in libr/util/uleb128.c. A crafted WebAssembly file can trigger a heap-based buffer over-read and application crash. The bundle provides no CVSS, CWE, fixed version, or vendor mitigation details.
Likely exposure
Exposure is most likely where radare2 1.3.0 is installed and used to inspect WebAssembly files, especially files received from external or untrusted sources.
Exploitation context
The provided sources cite a public radare2 GitHub issue. CISA KEV is false, and no cited source confirms active exploitation in the wild.
Researcher notes
The source evidence is narrow: it names radare2 1.3.0, the affected function, WebAssembly input, and crash behavior. It does not provide exploit maturity, patch version, CVSS scoring, or broader affected-version ranges.
Mitigation direction
- Inventory systems and pipelines using radare2 1.3.0.
- Avoid processing untrusted WebAssembly files with vulnerable radare2 versions.
- Check radare2 vendor guidance and release notes for a supported fix.
- Run file analysis in isolated environments where practical.
- Prioritize automated analysis systems that ingest external files.
Validation and detection
- Confirm installed radare2 versions across workstations and analysis pipelines.
- Identify workflows that submit WebAssembly files to radare2.
- Review crash logs for radare2 failures during WebAssembly parsing.
- Check the referenced GitHub issue for vendor discussion and status.
- Document whether compensating isolation controls are in place.
