Debian LTS Advisory DLA-3533-1 [email protected]

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.
