CVE-2015-3209 Matt Tait of Google's Project Zero security team discovered a flaw in the way QEMU's AMD PCnet Ethernet emulation handles multi-TMD packets with a length above 4096 bytes. A privileged guest user in a guest with an AMD PCNet ethernet card enabled can potentially use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. CVE-2015-4037 Kurt Seifried of Red Hat Product Security discovered that QEMU's user mode networking stack uses predictable temporary file names when the -smb option is used. An unprivileged user can use this flaw to cause a denial of service. For the oldstable distribution (wheezy), these problems have been fixed in version 1.1.2+dfsg-6+deb7u8. We recommend that you upgrade your qemu-kvm packages.
