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.
Limit image push/indexing to trusted sources until a fix is available. Where possible, run indexing so a single scanner failure cannot disrupt shared indexing capacity.
