high Nessus Plugin ID 96087
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 SUSE host is missing one or more security updates.

Description

This update for xen fixes the following issues :

- A Mishandling of SYSCALL singlestep during emulation which could have lead to privilege escalation. (XSA-204, bsc#1016340, CVE-2016-10013)

- CMPXCHG8B emulation failed to ignore operand size override which could have lead to information disclosure. (XSA-200, bsc#1012651, CVE-2016-9932)

- PV guests may have been able to mask interrupts causing a Denial of Service. (XSA-202, bsc#1014298, CVE-2016-10024)

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