high Nessus Plugin ID 83714

Synopsis

The remote SUSE host is missing one or more security updates.

Description

Xen was updated 4.4.2_01 to address three security issues and functional bugs.

The following vulnerabilities were fixed :

- Long latency MMIO mapping operations are not preemptible (XSA-125, CVE-2015-2752, bnc#922705)

- Unmediated PCI command register access in qemu (XSA-126, CVE-2015-2756, bnc#922706)

- Certain domctl operations may be abused to lock up the host (XSA-127, CVE-2015-2751, bnc#922709)

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.
