The archive_read_format_cab_read_header function in archive_read_support_format_cab.c in libarchive 3.2.2 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted file.

Security readout for executives and security teams

Plain-English summary

CVE-2016-10350 is a libarchive flaw where a specially crafted CAB archive can crash an application that tries to read it. The business impact is availability loss in services or tools that process untrusted archives, not confirmed data theft or code execution based on the provided sources.

Executive priority

Prioritize remediation for internet-facing or business-critical systems that accept uploaded archives. This is not supported as active exploitation or code execution in the provided evidence, but a reliable crash condition can still disrupt services.

Technical view

The issue is in archive_read_format_cab_read_header in archive_read_support_format_cab.c. libarchive 3.2.2 can perform a heap-based buffer over-read while parsing a crafted CAB file, causing application crash. Public advisories from Debian, Ubuntu, and Gentoo treated libarchive updates as security fixes.

Likely exposure

Exposure is most likely where servers, desktop tools, build systems, scanners, or upload workflows use vulnerable libarchive CAB parsing on files supplied by users or external parties. The bundle does not provide complete CPEs, downstream product names, or exact fixed upstream versions.

Exploitation context

The CVE description says remote attackers can trigger denial of service via a crafted file. KEV is false, and the provided sources do not show active exploitation. Treat exploit status as unconfirmed unless later vendor or government sources state otherwise.

Researcher notes

Evidence is limited: no CVSS vector, CWE, complete CPE list, or explicit upstream fixed release is provided in the bundle. Validate exposure through package metadata and vendor advisories, not the placeholder affected-product fields.

Mitigation direction

  • Apply libarchive security updates from the relevant OS or vendor advisory.
  • Check vendor guidance for exact fixed package versions in your distribution.
  • Reduce or isolate processing of untrusted CAB and archive files.
  • Run archive parsing in constrained services where crashes do not affect core systems.

Validation and detection

  • Inventory systems and applications using libarchive, especially version 3.2.2.
  • Confirm Debian, Ubuntu, Gentoo, or other vendor packages include the security update.
  • Review archive-ingestion services for crash logs tied to CAB processing.
  • Verify applications dynamically linked to libarchive load the patched library.
