Qlustar Security Advisory 1024192

Oct 24th, 2019

Summary:

A Qlustar security update bundle is a cumulative update of packages that are taken from upstream Debian/Ubuntu without modification. Only packages that are used in a typical HPC/Storage cluster installation are mentioned in Qlustar Security Advisories. Other non-HPC related updates also enter the Qlustar repository, but their functionality is not separately verified by the Qlustar team. To track these updates subscribe to the general security mailing lists of Debian/Ubuntu and/or CentOS.
