Description

Updated qemu packages fixes security vulnerabilities Qinghao Tang of QIHU 360 Inc. discovered an infinite loop issue in the NE2000 NIC emulation. A privileged guest user could use this flaw to mount a denial of service (QEMU process crash). (CVE-2015-5278) Qinghao Tang of QIHU 360 Inc. discovered a heap buffer overflow flaw in the NE2000 NIC emulation. A privileged guest user could use this flaw to mount a denial of service (QEMU process crash), or potentially to execute arbitrary code on the host with the privileges of the hosting QEMU process. (CVE-2015-5279) A flaw has been discovered in the QEMU emulator built with Virtual Network Device(virtio-net) support. If the guest's virtio-net driver did not support big or mergeable receive buffers, an issue could occur while receiving large packets over the tuntap/ macvtap interfaces. An attacker on the local network could use this flaw to disable the guest's networking; the user could send a large number of jumbo frames to the guest, which could exhaust all receive buffers, and lead to a denial of service. (CVE-2015-7295)
