medium Nessus Plugin ID 64782
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Nathanael Burton discovered that Keystone did not properly verify disabled users. An authenticated but disabled user would continue to have access rights that were removed. (CVE-2013-0282)

Jonathan Murray discovered that Keystone would allow XML entity processing. A remote unauthenticated attacker could exploit this to cause a denial of service via resource exhaustion. Authenticated users could also use this to view arbitrary files on the Keystone server.
(CVE-2013-1664, CVE-2013-1665).

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.
