Ubuntu 14.04 LTS : OpenStack Nova vulnerability (USN-2325-1)

high Nessus Plugin ID 77325

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2325-1 advisory.

 Alex Gaynor discovered that OpenStack Nova would sometimes respond with variable times when comparing authentication tokens. If nova were configured to proxy metadata requests via Neutron, a remote authenticated attacker could exploit this to conduct timing attacks and ascertain configuration details of another instance.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
