high Nessus Plugin ID 83965
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 openSUSE host is missing a security update.

Description

The XEN hypervisor was updated to fix two security issues :

- Fixed a buffer overflow in the floppy drive emulation, which could be used to denial of service attacks or potential code execution against the host.
(CVE-2015-3456)

- Xen did not initialize certain fields, which allowed certain remote service domains to obtain sensitive information from memory via a (1) XEN_DOMCTL_gettscinfo or (2) XEN_SYSCTL_getdomaininfolist request.
(CVE-2015-3340)

Solution

Update the affected xen packages.
