Vulnerability from github – Published: 2026-07-20 12:33 – Updated: 2026-07-20 12:33

Details

A flaw was found in claircore's apk package scanner. Malformed package-database data in a container layer can cause an out-of-bounds access that panics the scanner. If that panic is not recovered, the Clair indexer process can crash, leading to a denial of service.

Severity

4.3 (Medium)
