GHSA-W6V2-QCHM-GRJ7 Insecure permissions on user namespace / fakeroot temporary rootfs in Singularity

Impact Insecure permissions on temporary directories used in fakeroot or user namespace container execution. When a Singularity action command run, shell, exec is run with the fakeroot or user namespace option, Singularity will extract a container image to a temporary sandbox directory. Due to...

Medium: docker

Issue Overview: A flaw was found in the userns-remap feature of Docker. The root user in the remapped namespace can modify files under /var/lib/docker/, leading to possible privilege escalation to the root user in the host. The highest threat from this vulnerability is to data integrity...
