Fedora 17 : xen-4.1.5-2.fc17 (2013-7432)

medium Nessus Plugin ID 66435
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 Fedora host is missing a security update.

Description

PV guests can use non-preemptible long latency operations to mount a denial of service attack on the whole system [XSA-45, CVE-2013-1918], malicious guests can inject interrupts through bridge devices to mount a denial of service attack on the whole system [XSA-49, CVE-2013-1952]

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected xen package.
