 -------------------------------------------------------------------------

 Package : lxc Version : 1:3.1.0+really3.0.3-8+deb10u1 CVE ID : CVE-2022-47952

 LXC is a Linux Containers userspace tool set. Maher Azzouzi reported that the lxc-user-nic command, included in LXC, allowed unprivileged users to infer whether any file exists, even in protected directory trees.

 For Debian 10 buster, this problem has been fixed in version 1:3.1.0+really3.0.3-8+deb10u1.

 We recommend that you upgrade your lxc packages.
