Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2021-11-29 23:06:31 UTC
"Several user-accessible mount helpers use insecure defaults which allow
ext2/3/4 file systems to cause a denial of service (kernel panic) upon mounting a
crafted image.  This is especially relevant when mounts can be caused by
unprivileged users or are configured to happen automatically and completely


Fixed in 2.9.4.
