Описание
A flaw was found in crun. When crun is built with libkrun and a container is started rootful with passt networking (krun.use_passt), crun can execute attacker-controlled payload from the container image with host root privileges. The issue is a regression in crun 1.29. It affects crun >= 1.29
Отчет
This issue is a regression in crun 1.29 and requires the krun handler with passt networking.
Меры по смягчению последствий
Do not run untrusted images with krun and passt until a fixed crun is released.
