The _zip_read_eocd64 function in zip_open.c in libzip before 1.3.0 mishandles EOCD records, which allows remote attackers to cause a denial of service (memory allocation failure in _zip_cdir_grow in zip_dirent.c) via a crafted ZIP archive.

Security readout for executives and security teams

Plain-English summary

CVE-2017-14107 is a denial-of-service issue in libzip before 1.3.0. A specially crafted ZIP archive can make an affected application fail through excessive or failed memory allocation. Business impact is mainly service disruption where systems process untrusted ZIP files.

Executive priority

Treat this as a targeted availability risk, not a confirmed data theft issue. Prioritize internet-facing or business-critical systems that process ZIP uploads, then complete normal package patching for remaining assets.

Technical view

The issue is in libzip's _zip_read_eocd64 handling in zip_open.c. Malformed EOCD64 records can trigger memory allocation failure in _zip_cdir_grow in zip_dirent.c. The source bundle identifies libzip before 1.3.0 and an upstream commit as the fix context.

Likely exposure

Exposure is most likely in applications or services using libzip before 1.3.0 to open ZIP archives from users, partners, email, APIs, or automated ingestion pipelines. The source metadata does not name specific downstream products.

Exploitation context

The cited CVE description says remote attackers can cause denial of service with a crafted ZIP archive. The source bundle does not show CISA KEV listing or other evidence of active exploitation.

Researcher notes

Evidence is clear on affected library and failure mode, but incomplete on CVSS, CWE, named products, and exploitation. Avoid broad product claims. Validate through package versions, linked libraries, and distribution backport advisories rather than upstream version strings alone.

Mitigation direction

  • Inventory systems and packages that include libzip.
  • Upgrade libzip to 1.3.0 or a vendor-supported fixed package.
  • Apply relevant distribution security updates, including Debian LTS packages where applicable.
  • Limit untrusted ZIP processing until affected systems are updated.
  • Monitor vendor advisories for backported fixes in supported distributions.

Validation and detection

  • Check installed libzip package versions against vendor package metadata.
  • Confirm applications processing ZIP files link to a fixed libzip build.
  • Review upload and ingestion paths that accept untrusted ZIP archives.
  • Verify patched package deployment through asset or configuration management records.
  • Check service logs for repeated ZIP parsing crashes or memory allocation failures.
