Title
Claircore: claircore: denial of service via out-of-bounds slice in claircore's apk installed-database parser
Summary
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.
