=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
Summary:
Swift could cause the system to crash if it received specially crafted
requests over the network.
Software Description:
- swift: OpenStack distributed virtual object store
Details:
Peter Portante discovered that Swift did not properly handle requests with
old X-Timestamp values. An authenticated attacker could exploit this to
cause a denial of service via disk consumption.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 13.04:
python-swift 1.8.0-0ubuntu1.3
