Security readout for executives and security teams
Plain-English summary
CVE-2018-10186 affects radare2 2.5.0 and can crash analysis by triggering a heap-based buffer over-read through a crafted DEX file. The business risk is disruption to malware analysis, reverse engineering, or file-inspection workflows that process untrusted Android DEX content.
Executive priority
Prioritize remediation for teams using radare2 in automated security analysis or malware triage. For environments without radare2 2.5.0 or untrusted DEX processing, urgency is lower but inventory should still be confirmed.
Technical view
The flaw is a heap-based buffer over-read in r_hex_bin2str in libr/util/hex.c in radare2 2.5.0. The CVE description states remote attackers could cause denial of service using a crafted DEX file. No CVSS, CWE, fixed version, or patch details are provided in the source bundle.
Likely exposure
Exposure is most likely where radare2 2.5.0 processes DEX files from external or untrusted sources, especially automated analysis pipelines. The provided affected-product metadata is incomplete, but the CVE title and description identify radare2 2.5.0.
Exploitation context
The source bundle supports denial-of-service potential via crafted DEX input. It does not show active exploitation, CISA KEV listing, weaponized public exploitation, or privilege escalation. Treat exploitation as input-triggered crash risk unless vendor evidence says otherwise.
Researcher notes
The record lacks CVSS, CWE, CPE, and fixed-version data. The vulnerability is distinct from CVE-2017-15368. Analysis should avoid assuming broader product impact beyond radare2 2.5.0 and the DEX denial-of-service path described in the CVE.
Mitigation direction
- Check radare2 vendor guidance and issue 9915 for fixed-version information.
- Move analysis systems off radare2 2.5.0 when a supported fix is identified.
- Avoid processing untrusted DEX files with vulnerable radare2 versions.
- Isolate automated file-analysis workers that use radare2.
- Add crash monitoring around radare2-based DEX analysis workflows.
Validation and detection
- Inventory systems and containers for radare2 2.5.0.
- Identify pipelines that submit DEX files to radare2.
- Confirm whether DEX inputs can originate from untrusted users or external sources.
- Review radare2 crash logs around Android DEX processing.
- Track vendor issue 9915 for remediation status and affected-version clarification.
