Ubuntu 12.10 : keystone vulnerability (USN-1772-1)

medium Nessus Plugin ID 65641

Language:

Synopsis

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

Description

Guang Yee discovered that Keystone would not always perform all verification checks when configured to use PKI. If the keystone server was configured to use PKI and services or users requested online verification, an attacker could potentially exploit this to bypass revocation checks. Keystone uses UUID tokens by default in Ubuntu.

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.
