Fedora 20 : xen-4.3.1-6.fc20 (2013-23251)

high Nessus Plugin ID 71590
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

Disaggregated domain management security status update, IOMMU TLB flushing may be inadvertently suppressed Lock order reversal between page_alloc_lock and mm_rwlock, Hypercalls exposed to privilege rings 1 and 2 of HVM guests Insufficient TLB flushing in VT-d (iommu) code

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.
