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.

QEMU is a fast processor emulator: currently the package supports ARM, CRIS, i386, M68k (ColdFire), MicroBlaze, MIPS, PowerPC, SH4, SPARC and x86-64 emulation. By using dynamic translation it achieves reasonable speed while being easy to port on new host CPUs. QEMU has two operating modes:
