Ubuntu 14.04 LTS : QEMU vulnerabilities (USN-2692-1)

medium Nessus Plugin ID 85080

Language:

Synopsis

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

Description

Matt Tait discovered that QEMU incorrectly handled PIT emulation. In a non-default configuration, a malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. (CVE-2015-3214)

Kevin Wolf discovered that QEMU incorrectly handled processing ATAPI commands. A malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. (CVE-2015-5154)
