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

Releases

Packages

  • 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
Ubuntu 18.04

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