Synopsis
========

A vulnerability has been found in Ceph which can lead to root privilege
escalation.

Background
==========

Ceph is a distributed network file system designed to provide excellent
performance, reliability, and scalability.

Affected packages
=================

Package           Vulnerable    Unaffected
----------------  ------------  ------------
sys-cluster/ceph  < 17.2.6      >= 17.2.6

Description
===========

A vulnerability has been discovered in Ceph. Please review the CVE
identifier referenced below for details.

Impact
======

The ceph-crash.service runs the ceph-crash Python script as root. The
script is operating in the directory /var/lib/ceph/crash which is
controlled by the unprivileged ceph user (ceph:ceph mode 0750). The
script periodically scans for new crash directories and forwards the
content via `ceph crash post`.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ceph users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-cluster/ceph-17.2.6"
