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

high Nessus Plugin ID 77325

Synopsis

The remote Ubuntu host is missing a security update.

Description

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.

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 packages.
