Security readout for executives and security teams
Plain-English summary
This CVE describes a memory leak in GNU Binutils libbfd when processing crafted ELF files. If an exposed workflow analyzes attacker-supplied binaries, it may consume excessive memory and fail. The available sources do not provide CVSS scoring or evidence of active exploitation.
Executive priority
Treat this as a targeted denial-of-service risk for systems that analyze untrusted binaries. Prioritize remediation where ELF parsing is automated, exposed to uploads, or part of critical build and security operations.
Technical view
The issue is in decode_line_info in dwarf2.c within the Binary File Descriptor library, as distributed with GNU Binutils 2.29. A crafted ELF file can trigger memory consumption, resulting in denial of service. The source bundle names no broader affected version range or specific fixed release.
Likely exposure
Exposure is most likely in developer, build, reverse-engineering, scanning, or security-analysis systems that process untrusted ELF files using affected GNU Binutils/libbfd components. Internet-facing exposure is not established by the provided sources.
Exploitation context
The CVE states that remote attackers can cause denial of service using a crafted ELF file. The bundle marks KEV false and provides no cited evidence of active exploitation, public weaponization, or exploitation in the wild.
Researcher notes
Evidence is sparse: the provided record names GNU Binutils 2.29/libbfd and one Sourceware bug reference, but no CVSS, CWE, full affected range, or fixed version. Do not assume broader impact without vendor or distribution confirmation.
Mitigation direction
- Inventory systems using GNU Binutils 2.29 or libbfd-based ELF parsing.
- Check Sourceware and OS vendor guidance for CVE-2017-14930 fixes.
- Apply vendor-provided binutils/libbfd updates where available.
- Process untrusted ELF files in resource-limited, isolated environments.
- Avoid routing arbitrary uploaded ELF files into affected tooling.
Validation and detection
- Identify services and jobs that parse ELF files with binutils/libbfd.
- Confirm installed binutils versions on build and analysis hosts.
- Review package changelogs for CVE-2017-14930 or Sourceware bug 22191.
- Check whether untrusted binaries can reach automated analysis pipelines.
- Verify memory limits exist around file-processing workers.
