Ubuntu 13.10 : keystone vulnerability (USN-2061-1)

medium Nessus Plugin ID 71564

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Steven Hardy discovered that Keystone did not properly enforce trusts when using the ec2tokens API. An authenticated attacker could exploit this to retrieve a token not scoped to the trust and elevate privileges to the trustor's roles.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-keystone package.
