What is CVE-2015-3627?

The vulnerability in Docker Engine versions prior to 1.6.1 arises from improper handling of file descriptors passed to the pid-1 process. Specifically, the image's chroot is performed after the file descriptor is opened, which can be exploited through a symlink attack by local users. This flaw potentially allows these users to gain elevated privileges within the Docker container environment, posing significant security risks if left unaddressed.
