    Multiple security issues were discovered in LXD, a system container     and virtual machine manager, which could result in a bypass of security     restrictions or the execution of arbitrary commands.

    For the stable distribution (trixie), these problems have been fixed in     version 5.0.2+git20231211.1364ae4-9+deb13u7.

    We recommend that you upgrade your lxd packages.
