swift vulnerabilities
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in OpenStack Swift.

Software Description:
- swift: OpenStack distributed virtual object store

Details:

It was discovered that OpenStack Swift incorrectly handled tempurls. A
remote authenticated user in possession of a tempurl key authorized for PUT
could retrieve other objects in the same Swift account. (CVE-2015-5223)

Romain Le Disez and Örjan Persson discovered that OpenStack Swift
incorrectly closed client connections. A remote attacker could possibly use
this issue to consume resources, resulting in a denial of service.
(CVE-2016-0737, CVE-2016-0738)

Update instructions:

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

Ubuntu 14.04 LTS:
  python-swift                    1.13.1-0ubuntu1.5
  swift                           1.13.1-0ubuntu1.5

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