Ubuntu 12.04 LTS : nova vulnerability (USN-1501-1)

low Nessus Plugin ID 59954

Language:

Synopsis

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

Description

Dan Prince discovered that the Nova scheduler, when using DifferentHostFilter or SameHostFilter, would make repeated database instance lookup calls based on passed scheduler hints. An authenticated attacker could use this to cause a denial of service.

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-nova package.
