ceph vulnerability
==========================================================================

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

- Ubuntu 19.04
- Ubuntu 18.04 LTS

Summary:

Ceph could be made to crash if it received specially crafted network
traffic.

Software Description:
- ceph: distributed storage and file system

Details:

Abhishek Lekshmanan discovered that the RADOS gateway implementation in
Ceph did not handle client disconnects properly in some situations. A
remote attacker could use this to cause a denial of service.

Update instructions:

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

Ubuntu 19.04:
  ceph                            13.2.6-0ubuntu0.19.04.3
  radosgw                         13.2.6-0ubuntu0.19.04.3

Ubuntu 18.04 LTS:
  ceph                            12.2.12-0ubuntu0.18.04.2
  radosgw                         12.2.12-0ubuntu0.18.04.2

In general, a standard system update will make all the necessary changes.
