Synopsis

The remote Debian host is missing a security update.

Description

Multiple vulnerabilities were discovered in qemu-kvm, a full virtualization solution for Linux hosts on x86 hardware with x86 guests based on the Quick Emulator(Qemu).

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-kvm 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 kvm, qemu-kvm, and qemu-kvm-dbg packages.
