Debian DLA-539-1 : qemu-kvm security update
High Nessus Plugin ID 91919
SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral vulnerabilities were discovered in qemu-kvm, a full virtualization solution for Linux hosts on x86 hardware with x86 guests.
Wei Xiao and Qinghao Tang of 360.cn Inc discovered an out-of-bounds read and write flaw in the QEMU VGA module. A privileged guest user could use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process.
Zuozhi Fzz of Alibaba Inc discovered potential integer overflow or out-of-bounds read access issues in the QEMU VGA module. A privileged guest user could use this flaw to mount a denial of service (QEMU process crash).
For Debian 7 'Wheezy', these problems have been fixed in version 1.1.2+dfsg-6+deb7u13.
We recommend that you upgrade your qemu-kvm packages.

SolutionUpgrade the affected kvm, qemu-kvm, and qemu-kvm-dbg packages.
