slurm-llnl vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Slurm could be made to send data to an arbitrary unix socket on the host.

Software Description:
- slurm-llnl: Simple Linux Utility for Resource Management

Details:

It was discovered that Slurm did not properly handle access control when
dealing with RPC traffic through PMI2 and PMIx, which could allow an
unprivileged user to send data to an arbitrary unix socket on the host.
An attacker could possibly use this issue to execute arbitrary code as
the root user.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:
