Hi,

The following vulnerability was published for docker.io.

CVE-2018-15664[0]:
| In Docker through 18.06.1-ce-rc2, the API endpoints behind the 'docker
| cp' command are vulnerable to a symlink-exchange attack with Directory
| Traversal, giving attackers arbitrary read-write access to the host
| filesystem with root privileges, because daemon/archive.go does not do
| archive operations on a frozen filesystem (or from within a chroot).


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Please adjust the affected versions in the BTS as needed.

Subject: docker.io: CVE-2018-15664 - upstream backport of patch for 18.09

Date: Sat, 8 Jun 2019 22:31:03 -0400

Hello,

Is any help needed on this? Upstream has a backport of the patch for the
18.09 series (same as Unstable):

  https://github.com/docker/engine/pull/253

Hopefully it won't be too much work to incorporate it.

thanks and regards
Afif

  Hi,

thanks for reaching out. I applied the patch, that is no problem.
However the new tests that were added makes my machine go crazy and
reach the maximum number of process. Right now I'm configured like that:

    $ ulimit -u
    62688

I will bumb this number but I also want to check a bit more in details
what's happening and report that upstream, as I don't know if this is
expected behavior or not.

You can checkout the branch at
https://salsa.debian.org/docker-team/docker/tree/arnaudr/cve-2018-15664
and try it by yourself if you're curious.

In the meantime, I reached out to the release team at #930293 to prepare
for the next unblock.

So things are in progress, no need for help on this particular issue,
but in general if you're interested in the docker package, then help
with the packaging is more than welcome :)

  Arnaud
