01 Jan 2023 — lxc-user-nic in lxc through 5.0.1 is installed setuid root, and may allow local users to infer whether any file exists, even within a protected directory tree, because "Failed to open" often indicates that a file does not exist, whereas "does not refer to a network namespace path" often indicates that a file exists. NOTE: this is different from CVE-2018-6556 because the CVE-2018-6556 fix design was based on the premise that "we will report back to the user that the open() failed but the user has no way of k... • https://github.com/MaherAzzouzi/CVE-2022-47952 • CWE-203: Observable Discrepancy •

11 Feb 2019 — runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/sel... • https://packetstorm.news/files/id/165197 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-672: Operation on a Resource after Expiration or Release •
CVSS: 3.3EPSS: 0%CPEs: 9EXPL: 0CVE-2018-6556 – The lxc-user-nic component of LXC allows unprivileged users to open arbitrary files
https://notcve.org/view.php?id=CVE-2018-6556
06 Aug 2018 — lxc-user-nic when asked to delete a network interface will unconditionally open a user provided path. This code path may be used by an unprivileged user to check for the existence of a path which they wouldn't otherwise be able to reach. It may also be used to trigger side effects by causing a (read-only) open of special kernel files (ptmx, proc, sys). Affected releases are LXC: 2.0 versions above and including 2.0.9; 3.0 versions above and including 3.0.0, prior to 3.0.2.
