Security readout for executives and security teams
Plain-English summary
NASM versions through 2.14rc16 are reported to have memory leaks that could cause denial of service. This matters mainly where NASM processes untrusted or automated inputs, such as build systems. The public record does not provide CVSS, exploit evidence, or a confirmed fixed version.
Executive priority
Treat this as a targeted build-tool resilience issue, not a confirmed enterprise-wide emergency. Prioritize environments where external code can reach NASM, especially shared CI or hosted build services.
Technical view
CVE-2018-19213 describes memory leaks in Netwide Assembler through 2.14rc16, related to nasm_malloc in nasmlib/malloc.c. The source bundle does not identify a CWE, CVSS score, proof of exploitation, or remediation details beyond the NASM Bugzilla reference.
Likely exposure
Exposure is most likely where NASM through 2.14rc16 is installed and used to assemble untrusted, third-party, or automatically submitted source files. The sources do not indicate remote network exposure by default.
Exploitation context
The CVE is not listed as KEV, and the provided sources do not state active exploitation. The described impact is potential denial of service through memory leaks, but exploitability details are incomplete.
Researcher notes
The public metadata is sparse: no CVSS, CWE, CPE, patch version, or exploit status is provided in the source bundle. Analysis should remain tied to NASM through 2.14rc16 and the nasm_malloc memory-leak description.
Mitigation direction
- Inventory NASM installations and versions across developer, CI, and build systems.
- Check NASM Bugzilla and vendor packaging guidance for fixed or recommended versions.
- Avoid assembling untrusted files with affected NASM versions.
- Use build timeouts and memory limits around NASM jobs.
- Prioritize updates where NASM handles external submissions.
Validation and detection
- Confirm whether NASM is installed in CI, build images, or developer tooling.
- Record NASM versions and identify any through 2.14rc16.
- Review build workflows for untrusted or third-party assembly inputs.
- Check package manager changelogs for CVE-2018-19213 references.
- Verify resource limits exist for automated assembly jobs.
