| Description: | Description:
The remote host is missing an update to qemu-kvm
announced via advisory USN-1145-1.
Details:
It was discovered that QEMU did not properly perform validation of I/O
operations from the guest which could lead to heap corruption. An attacker
could exploit this to cause a denial of service of the guest or possibly
execute code with the privileges of the user invoking the program.
(CVE-2011-1750)
Nelson Elhage discoverd that QEMU did not properly handle memory when
removing ISA devices. An attacker could exploit this to cause a denial of
service of the guest or possibly execute code with the privileges of the
user invoking the program. (CVE-2011-1751)
When using QEMU with libvirt or virtualization management software based on
libvirt such as Eucalyptus and OpenStack, QEMU guests are individually isolated
by an AppArmor profile by default in Ubuntu.
Solution:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.04:
qemu-kvm 0.14.0+noroms-0ubuntu4.1
Ubuntu 10.10:
qemu-kvm 0.12.5+noroms-0ubuntu7.5
qemu-kvm-extras 0.12.5+noroms-0ubuntu7.5
qemu-kvm-extras-static 0.12.5+noroms-0ubuntu7.5
Ubuntu 10.04 LTS:
qemu-kvm 0.12.3+noroms-0ubuntu9.9
qemu-kvm-extras 0.12.3+noroms-0ubuntu9.9
qemu-kvm-extras-static 0.12.3+noroms-0ubuntu9.9
