Ubuntu Security Notice USN-2001-1
October 23, 2013

swift vulnerability

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

Ubuntu 12.10:
python-swift 1.7.4-0ubuntu2.3

Ubuntu 12.04 LTS:
python-swift 1.4.8-0ubuntu2.3

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