What is CVE-2015-3629?

A vulnerability in Libcontainer 1.6.0 used by Docker Engine enables local users to perform a 'mount namespace breakout'. This flaw allows malicious users to exploit symlink attacks in container images, potentially granting them the ability to write to arbitrary files on the host system when respawning a container. Proper security measures are essential to mitigate these risks and protect the integrity of the host environment.
