March 17, 2020

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

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

- Ubuntu 19.10
- Ubuntu 18.04 LTS

Summary:

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

Software Description:
- ceph: distributed storage and file system

Details:

Or Friedman discovered that Ceph incorrectly handled disconnects. A remote
authenticated attacker could possibly use this issue to cause Ceph to
consume resources, leading to a denial of service.

package versions:

Ubuntu 19.10:
  ceph                            14.2.4-0ubuntu0.19.10.2
  ceph-base                       14.2.4-0ubuntu0.19.10.2
  ceph-common                     14.2.4-0ubuntu0.19.10.2

Ubuntu 18.04 LTS:
  ceph                            12.2.12-0ubuntu0.18.04.5
  ceph-base                       12.2.12-0ubuntu0.18.04.5
  ceph-common                     12.2.12-0ubuntu0.18.04.5
