SUSE SLES10 Security Update : Xen (SUSE-SU-2014:1691-1)

high Nessus Plugin ID 83651
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

Xen has been updated to fix six security issues :

- Guest effectable page reference leak in MMU_MACHPHYS_UPDATE handling (CVE-2014-9030).

- Insufficient bounding of 'REP MOVS' to MMIO emulated inside the hypervisor (CVE-2014-8867).

- Missing privilege level checks in x86 emulation of far branches (CVE-2014-8595).

- Guest user mode triggerable VM exits not handled by hypervisor (bnc#903850).

- Missing privilege level checks in x86 HLT, LGDT, LIDT, and LMSW emulation (CVE-2014-7155).

- Hypervisor heap contents leaked to guests (CVE-2014-4021).

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.

Solution

Update the affected Xen packages
