LXC 1.0.9 and LXC 2.0.6 also fix CVE-2016-8649. CVE-2016-8649 was reported by Roman Fiedler from AIT and is a way to access the host filesystem and therefore escaping the container through an inherited dirfd to the host's /proc. This issue is possible because the Linux kernel doesn't prevent root in the container from attaching (with ptrace) to the lxc-attach process then running as real root. Eric Biederman submitted a set of ptrace fixes to the Linux kernel which will prevent this kind of attack from being possible in the future. The fix we're releasing today, simply stops passing a full dirfd to /proc and instead only passes the one file we actually care about, reducing the impact from an attacker attaching to the process. The detailed changelogs can be found at: - https://linuxcontainers.org/lxc/news/ - https://linuxcontainers.org/lxcfs/news/ - https://linuxcontainers.org/lxd/news/ As a reminder, the 2.0 series of all of those is supported for bugfix and security updates up until June 2021. The LXC 1.0.x branch is supported until June 2019 with critical bugfixes and security updates only from this point on. Thanks to everyone who contributed to those projects and helped make this possible!
