Off-by-one error in the extracthalf function in dpkg-deb/extract.c in the dpkg-deb component in Debian dpkg 1.16.x before 1.16.17 and 1.17.x

Off-by-one error in the extracthalf function in dpkg-deb/extract.c in the dpkg-deb component in Debian dpkg 1.16.x before 1.16.17 and 1.17.x before 1.17.26 allows remote attackers to execute arbitrary code via the archive magic version number in an "old-style" Debian binary package, which triggers a stack-based buffer overflow.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
