CVE-2026-91094 debian dpkg
debian dpkg: no CVSS score yet.
A directory traversal bug was discovered when unpacking 3.0 (quilt) source packages, where the packaging tarball could contain the quilt database directory (.pc) with attacker controlled symlinks, where that in combination with patches that would fail to apply, could be used to make the code used to restore the backup files to either modify or remove the files pointed to by the attacker controlled symlinks.

Explain CVE-2026-91094 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-91094?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-91094?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-91094 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
