The remote host is missing an update to slurm-llnl announced via advisory DSA 1776-1.

It was discovered that the Simple Linux Utility for Resource Management (SLURM), a cluster job management and scheduling system, did not drop the supplemental groups. These groups may be system groups with elevated privileges, which may allow a valid SLURM user to gain elevated privileges. The old stable distribution (etch) does not contain a slurm-llnl package. For the stable distribution (lenny), this problem has been fixed in version 1.3.6-1lenny3. For the unstable distribution (sid), this problem has been fixed in version 1.3.15-1. We recommend that you upgrade your slurm-llnl package.
