security advisoryhigh severityprivilege escalationArch Linux ASA-201505-6 High: Docker Privilege Escalation Threats
The package docker before version 1:1.6.1-1 is vulnerable to multiple issues including but not limited to privilege escalation, symlink traversal, unauthorized configuration modification, information disclosure and policy profile escalation. . Arch Linux Security Advisory ASA-201505-6 ======================================== Severity: High Date : 2015-05-08 CVE-ID : CVE-2015-3627 CVE-2015-3629 CVE-2015-3630 CVE-2015-3631 Package : docker Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/title/CVE Summary ====== The package docker before version 1:1.6.1-1 is vulnerable to multiple issues including but not limited to privilege escalation, symlink traversal, unauthorized configuration modification, information disclosure and policy profile escalation. Resolution ========= Upgrade to 1:1.6.1-1. # pacman -Syu "docker> =1:1.6.1-1" The problems have been fixed upstream in version 1.6.1. Workaround ========= None. Description ========== - CVE-2015-3627 (privilege escalation) The file-descriptor passed by libcontainer to the pid-1 process of a container has been found to be opened prior to performing the chroot, allowing insecure open and symlink traversal. This allows malicious container images to trigger a local privilege escalation. - CVE-2015-3629 (privilege escalation) Symlink traversal on container respawn allows local privilege escalation. Libcontainer version 1.6.0 introduced changes which facilitated a mount namespace breakout upon respawn of a container. This allowed malicious images to write files to the host system and escape containerization. - CVE-2015-3630 (unauthorized modification) Several paths underneath /proc were writable from containers, allowing global system manipulation and configuration. These paths included /proc/asound, /proc/timer_stats, /proc/latency_stats, and /proc/fs. By allowing writes to /proc/fs, it has been noted that CIFS volumes could be forced into a protocol downgrade attack by a rootuser operating inside of a container. Machines having loaded the timer_stats module were vulnerable to having this mechanism enabled and consumed by a container. - CVE-2015-3631 (policy profile escalation) By allowing volumes to override files of /proc within a mount namespace, a user could specify arbitrary policies for Linux Security Modules, including setting an unconfined policy underneath AppArmor, or a docker_t policy for processes managed by SELinux. In all versions of Docker up until 1.6.1, it is possible for malicious images to configure volume mounts such that files of proc may be overridden. Impact ===== A remote attacker is able to escalate privileges via unsafe symlink traversal, modify the configuration of the host system or disclose information via specific writable descriptors in /proc or escalate the LSM policy profiles by overriding files of /proc.
