Youki is a container runtime written in Rust. In versions 0.5.6 and below, the initial validation of the source /dev/nul

Youki is a container runtime written in Rust. In versions 0.5.6 and below, the initial validation of the source /dev/null is insufficient, allowing container escape when youki utilizes bind mounting the container's /dev/null as a file mask. This issue is fixed in version 0.5.7.
