high Nessus Plugin ID 103714
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 Debian host is missing a security update.

Description

Multiple vulnerabilities were discovered in qemu, a fast processor emulator. The Common Vulnerabilities and Exposures project identifies the following problems :

CVE-2017-14167

Incorrect validation of multiboot headers could result in the execution of arbitrary code.

CVE-2017-15038

When using 9pfs qemu-kvm is vulnerable to an information disclosure issue. It could occur while accessing extended attributes of a file due to a race condition. This could be used to disclose heap memory contents of the host.

For Debian 7 'Wheezy', these problems have been fixed in version 1.1.2+dfsg-6+deb7u24.

We recommend that you upgrade your qemu packages.

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

Solution

Upgrade the affected packages.
