Ubuntu 12.04 LTS : keystone vulnerability (USN-1564-1)

medium Nessus Plugin ID 62072

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Dolph Mathews discovered that when roles are granted and revoked to users in Keystone, pre-existing tokens were not updated or invalidated to take the new roles into account. An attacker could use this to continue to access resources that have been revoked.

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 keystone and / or python-keystone packages.
