May 06, 2014

swift vulnerability

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

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS


OpenStack Swift would allow unintended access to files over the network.

Software Description:
- swift: OpenStack distributed virtual object store


Samuel Merritt discovered a timing attack vulnerability in OpenStack Swift.
If Swift was configured to use the TempURL middleware, an attacker could
exploit this to guess valid secret URLs and obtain unintended access to
objects publicly shared with specific recipients.

Update instructions:

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

Ubuntu 13.10:
  python-swift                    1.10.0-0ubuntu1.1

Ubuntu 12.10:
  python-swift                    1.7.4-0ubuntu2.4

Ubuntu 12.04 LTS:
  python-swift                    1.4.8-0ubuntu2.4

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