Multiple directory traversal vulnerabilities in Lintian 1.23.x through 1.23.28, 1.24.x through 1.24.2.1, and 2.x before 2.3.2 allow remote attackers to overwrite arbitrary files or obtain sensitive information via vectors involving (1) control field names, (2) control field values, and (3) control files of patch systems.

Security readout for executives and security teams

This is an old Lintian flaw where specially crafted Debian package metadata could traverse directories. If an organization ran vulnerable Lintian against untrusted packages, files could be overwritten or sensitive files exposed. The sources do not show active exploitation or a CVSS score. Exposure is most likely in Debian or Ubuntu build, packaging, QA, or CI systems that run vulnerable Lintian versions on packages from outside trusted maintainers. General production servers are unlikely to be exposed unless they process untrusted Debian packages with Lintian. Treat this as a targeted packaging-tool risk, not a broad internet-facing emergency. Prioritize patching build and package-review infrastructure that handles third-party Debian artifacts, especially where Lintian runs with write access to sensitive workspaces. Mitigation focus: Upgrade Lintian using the fixed Debian or Ubuntu security packages referenced by vendor advisories.; Ensure Lintian 2.x deployments are at version 2.3.2 or later, or a vendor-backported fixed build.; Avoid running vulnerable Lintian against untrusted packages until patched..
