SUSE SLED12 / SLES12 Security Update : qemu (SUSE-SU-2016:0459-1)

critical Nessus Plugin ID 88803
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 fixes the following security issues :

- Enforce receive packet size, thus eliminating buffer overflow and potential security issue. (bsc#957162 CVE-2015-7512)

- Infinite loop in processing command block list.
CVE-2015-8345 (bsc#956829) :

This update also fixes a non-security bug :

- Due to space restrictions in limited bios data areas, don't create mptable if vcpu count is 'high' (ie more than ~19). (bsc#954864) (No supported guests are negatively impacted by this change, which is taken from upstream seabios)

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.
