CVE-2022-47952 1 Linuxcontainers 1 Lxc 2023-01-09 N/A 3.3 LOW
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 knowing why it failed"; however, in many realistic cases, there are no plausible reasons for failing except that the file does not exist.
CVE-2019-5736 13 Apache, Canonical, D2iq and 10 more 19 Mesos, Ubuntu Linux, Dc\/os and 16 more 2021-12-16 9.3 HIGH 8.6 HIGH
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/self/exe.
CVE-2017-18641 1 Linuxcontainers 1 Lxc 2020-02-12 9.3 HIGH 8.1 HIGH
In LXC 2.0, many template scripts download code over cleartext HTTP, and omit a digital-signature check, before running it to bootstrap containers.
CVE-2015-1340 1 Linuxcontainers 1 Lxd 2019-10-09 6.8 MEDIUM 8.1 HIGH
LXD before version 0.19-0ubuntu5 doUidshiftIntoContainer() has an unsafe Chmod() call that races against the stat in the Filepath.Walk() function. A symbolic link created in that window could cause any file on the system to have any mode of the attacker's choice.
CVE-2017-5985 1 Linuxcontainers 1 Lxc 2019-10-02 2.1 LOW 3.3 LOW
lxc-user-nic in Linux Containers (LXC) allows local users with a lxc-usernet allocation to create network interfaces on the host and choose the name of those interfaces by leveraging lack of netns ownership check.
CVE-2015-1335 2 Canonical, Linuxcontainers 2 Ubuntu Linux, Lxc 2019-05-31 7.2 HIGH N/A
lxc-start in lxc before 1.0.8 and 1.1.x before 1.1.4 allows local container administrators to escape AppArmor confinement via a symlink attack on a (1) mount target or (2) bind mount source.
CVE-2015-1334 1 Linuxcontainers 1 Lxc 2019-05-31 4.6 MEDIUM N/A
attach.c in LXC 1.1.2 and earlier uses the proc filesystem in a container, which allows local container users to escape AppArmor or SELinux confinement by mounting a proc filesystem with a crafted (1) AppArmor profile or (2) SELinux label.
CVE-2015-1331 1 Linuxcontainers 1 Lxc 2019-05-31 4.9 MEDIUM N/A
lxclock.c in LXC 1.1.2 and earlier allows local users to create arbitrary files via a symlink attack on /run/lock/lxc/*.
CVE-2018-6556 4 Canonical, Linuxcontainers, Opensuse and 1 more 6 Ubuntu Linux, Lxc, Leap and 3 more 2019-05-31 2.1 LOW 3.3 LOW
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.
CVE-2016-8649 1 Linuxcontainers 1 Lxc 2018-10-26 9.0 HIGH 9.1 CRITICAL
lxc-attach in LXC before 1.0.9 and 2.x before 2.0.6 allows an attacker inside of an unprivileged container to use an inherited file descriptor, of the host's /proc, to access the rest of the host's filesystem via the openat() family of syscalls.
CVE-2016-10124 1 Linuxcontainers 1 Lxc 2017-11-12 5.0 MEDIUM 8.6 HIGH
An issue was discovered in Linux Containers (LXC) before 2016-02-22. When executing a program via lxc-attach, the nonpriv session can escape to the parent session by using the TIOCSTI ioctl to push characters into the terminal's input buffer, allowing an attacker to escape the container.
CVE-2014-1425 2 Canonical, Linuxcontainers 2 Ubuntu Linux, Cgmanager 2015-01-08 2.1 LOW N/A
cmanager 0.32 does not properly enforce nesting when modifying cgroup properties, which allows local users to set cgroup values for all cgroups via unspecified vectors.
CVE-2013-6441 1 Linuxcontainers 1 Lxc 2014-02-18 7.2 HIGH N/A
The lxc-sshd template (templates/lxc-sshd.in) in LXC before 1.0.0.beta2 uses read-write permissions when mounting /sbin/init, which allows local users to gain privileges by modifying the init file.
