Package : qemu
CVE ID : CVE-2014-3689 CVE-2014-7815
Debian Bug : 765496

Several vulnerabilities were discovered in qemu, a fast processor
emulator.

CVE-2014-3689

The Advanced Threat Research team at Intel Security reported that
guest provided parameter were insufficiently validated in
rectangle functions in the vmware-vga driver. A privileged guest
user could use this flaw to write into qemu address space on the
host, potentially escalating their privileges to those of the
qemu host process.

CVE-2014-7815

James Spadaro of Cisco reported insufficiently sanitized
bits_per_pixel from the client in the QEMU VNC display driver. An
attacker having access to the guest's VNC console could use this
flaw to crash the guest.

For the stable distribution (wheezy), these problems have been fixed in
version 1.1.2+dfsg-6a+deb7u5.

For the unstable distribution (sid), these problems have been fixed in
version 2.1+dfsg-7.

We recommend that you upgrade your qemu packages.
