Ubuntu 12.10 / 13.04 : keystone vulnerabilities (USN-2002-1)

medium Nessus Plugin ID 70581

Synopsis

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

Description

Chmouel Boudjnah discovered that Keystone did not properly invalidate user tokens when a tenant was disabled which allowed an authenticated user to retain access via the token. (CVE-2013-4222)

Kieran Spear discovered that Keystone did not properly verify PKI tokens when performing revocation when using the memcache and KVS backends. An authenticated attacker could exploit this to bypass intended access restrictions. (CVE-2013-4294).

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.
