Package : util-linux
CVE ID : CVE-2021-3995 CVE-2021-3996
The Qualys Research Labs discovered two vulnerabilities in util-linux's
libmount. These flaws allow an unprivileged user to unmount other users'
filesystems that are either world-writable themselves or mounted in a
world-writable directory (CVE-2021-3996), or to unmount FUSE filesystems
that belong to certain other users (CVE-2021-3995).
For the stable distribution (bullseye), these problems have been fixed in
version 2.36.1-8+deb11u1.
We recommend that you upgrade your util-linux packages.
