**Name of the Vulnerable Software and Affected Versions** OpenStack Compute (Nova) versions 2013.2 through 2013.2.2 **Description** The issue allows remote authenticated users to bypass the quota limit and cause a denial of service by requesting a VM be put into rescue and then deleting the image, due to the VMWare driver not properly putting VMs into RESCUE status. **Recommendations** For OpenStack Compute (Nova) versions 2013.2 through 2013.2.2, consider restricting access to the VM rescue functionality to prevent unauthorized users from exploiting this issue. As a temporary workaround, consider implementing additional quota checks to limit resource consumption. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** OpenStack Compute (Nova) versions Folsom through Grizzly and earlier **Description** The issue allows remote attackers to cause a denial of service by consuming the connection pool. This can be achieved by sending multiple requests with long strings to an instance console and then retrieving the console log. The estimated number of potentially affected devices worldwide is not specified. **Recommendations** For OpenStack Compute (Nova) versions Folsom through Grizzly and earlier, consider disabling the use of Apache Qpid for the RPC backend as a temporary workaround to minimize the risk of exploitation. Restrict access to instance consoles to prevent abuse. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
