========================================================================== Ubuntu Security Notice USN-2828-1 December 03, 2015
qemu, qemu-kvm vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10 - Ubuntu 15.04 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in QEMU.
Software Description: - qemu: Machine emulator and virtualizer - qemu-kvm: Machine emulator and virtualizer
Details:
Jason Wang discovered that QEMU incorrectly handled the virtio-net device. A remote attacker could use this issue to cause guest network consumption, resulting in a denial of service. (CVE-2015-7295)
Qinghao Tang and Ling Liu discovered that QEMU incorrectly handled the pcnet driver when used in loopback mode. 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-2015-7504)
