Debian: udisks2 Important DoS Local Privilege Escalation DLA-4284-1

Michael Imfeld discovered an out-of-bounds read vulnerability in udisks2,
which may result in denial of service (daemon process crash), or in
mapping an internal file descriptor from the daemon process onto a loop
device, resulting in local privilege escalation.


For Debian 11 bullseye, this problem has been fixed in version
2.9.2-2+deb11u3.

We recommend that you upgrade your udisks2 packages.
