New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionThis update for qemu fixes several issues. This security issue was fixed :
- CVE-2018-3639: Spectre v4 vulnerability mitigation support for KVM guests (bsc#1092885). Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. This patch permits the new x86 cpu feature flag named 'ssbd' to be presented to the guest, given that the host has this feature, and KVM exposes it to the guest as well.
For this feature to be enabled please use the qemu commandline
-cpu $MODEL,+spec-ctrl,+ssbd so the guest OS can take advantage of the feature. spec-ctrl and ssbd support is also required in the host. This feature was added :
- Add support for block resize support for xen disks through the monitor
The update package also includes non-security fixes. See advisory for details.
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.
