Debian DSA-3088-1 : qemu-kvm - security update

medium Nessus Plugin ID 79729


The remote Debian host is missing a security-related update.


Paolo Bonzini of Red Hat discovered that the blit region checks were insufficient in the Cirrus VGA emulator in qemu-kvm, a full virtualization solution on x86 hardware. 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.


Upgrade the qemu-kvm packages.

For the stable distribution (wheezy), this problem has been fixed in version 1.1.2+dfsg-6+deb7u6.
