An out-of-bounds read flaw exists in parse_file_info in archive_read_support_format_iso9660.c in libarchive 3.3.2 when extracting a specially crafted iso9660 iso file, related to archive_read_format_iso9660_read_header.

Security readout for executives and security teams

Plain-English summary

libarchive 3.3.2 can read outside expected memory while extracting a malicious ISO9660 image. Business risk is highest where systems automatically unpack or inspect untrusted ISO files. The bundle provides no KEV listing or active exploitation evidence.

Executive priority

Treat this as a moderate remediation item unless your environment processes untrusted ISO files automatically. In those workflows, prioritize patching because attacker-controlled archives can reach vulnerable parsing code without user awareness.

Technical view

The flaw is an out-of-bounds read in parse_file_info within archive_read_support_format_iso9660.c, reached through archive_read_format_iso9660_read_header when handling a specially crafted ISO9660 ISO. The bundle names libarchive 3.3.2; broader affected ranges are not provided.

Likely exposure

Exposure is likely where libarchive processes untrusted ISO9660 images, including upload, scanning, extraction, backup, or forensic workflows. Confirm actual exposure by inventorying libarchive package versions and identifying automated ISO handling paths.

Exploitation context

The described trigger requires a specially crafted ISO9660 ISO and extraction or header processing by vulnerable libarchive. KEV is false, and the supplied sources do not state active exploitation or exploit availability.

Researcher notes

The bundle lacks CVSS, CWE, precise fixed versions, and complete affected-version ranges. Analysis should stay anchored to libarchive 3.3.2 and distro security updates. Do not infer active exploitation from advisory publication alone.

Mitigation direction

  • Update libarchive through the relevant OS or vendor security advisory.
  • Prioritize systems that automatically process untrusted ISO files.
  • Temporarily restrict ISO extraction from untrusted sources where updates are delayed.
  • Monitor vendor guidance for exact fixed package versions.
  • Review dependent applications that bundle libarchive separately.

Validation and detection

  • Inventory installed and bundled libarchive versions across servers and images.
  • Check whether ISO9660 extraction is enabled in exposed workflows.
  • Verify Debian, Ubuntu, Gentoo, or vendor package advisories are applied.
  • Confirm scanners or upload services reject unexpected ISO inputs when needed.
  • Record systems where version range cannot be proven from package metadata.
