Debian DSA-3087-1 : qemu - security update

medium Nessus Plugin ID 79728


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, a fast processor emulator. 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 packages.

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