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

Ubuntu Security Notice (C) 2013 Canonical, Inc. / NASL script (C) 2013 Tenable Network Security, Inc.


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.

Solution :

Update the affected python-keystone package.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.6
(CVSS2#E:F/RL:OF/RC:C)
Public Exploit Available : true
