Subject: slurm-llnl: CVE-2016-10030

Date: Sat, 07 Jan 2017 07:34:45 +0100

Source: slurm-llnl
Version: 14.03.9-5
Severity: grave
Tags: upstream patch security fixed-upstream
Justification: user security hole

Hi,

the following vulnerability was published for slurm-llnl.

CVE-2016-10030[0]:
| The _prolog_error function in slurmd/req.c in Slurm before 15.08.13,
| 16.x before 16.05.7, and 17.x before 17.02.0-pre4 has a vulnerability
| in how the slurmd daemon informs users of a Prolog failure on a compute
| node. That vulnerability could allow a user to assume control of an
| arbitrary file on the system. Any exploitation of this is dependent on
| the user being able to cause or anticipate the failure (non-zero return
| code) of a Prolog script that their job would run on. This issue
| affects all Slurm versions from 0.6.0 (September 2005) to present.
| Workarounds to prevent exploitation of this are to either disable your
| Prolog script, or modify it such that it always returns 0 ("success")
| and adjust it to set the node as down using scontrol instead of relying
| on the slurmd to handle that automatically. If you do not have a Prolog
| set you are unaffected by this issue.

I'm not to familiar with slurm, but looking at the description and
code this should be the case. It is fixed upstream.

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.

And now included with the recent upload of some hours ago to unstable.
So closing with that version.

If you want to fix this for jessie, you should start with the patch
from the 15.08 branch and it should be easy to backport:
https://github.com/SchedMD/slurm/commit/465c98ccff9f1e0018e6a0e6e86ee485ae480ae6

At least it was for me for the version in wheezy. I attach my backported
patch for reference. But I don't really know how to test it...
