Symlink Attack in Libcontainer and Docker Engine
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | github.com/docker/docker | < 1.6.1 | 1.6.1 |
Details
As written in the advisory (Markdown source, shown as plain text).
Libcontainer and Docker Engine before 1.6.1 opens the file-descriptor passed to the pid-1 process before performing the chroot, which allows local users to gain privileges via a symlink attack in an image.
