Description:Summary:
Several vulnerabilities were discovered
in qemu-kvm, a full virtualization solution on x86 hardware.

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.

Affected Software/OS:
qemu-kvm on Debian Linux

Solution:
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.

CVSS Score:
