Ubuntu 10.04 LTS / 10.10 / 11.04 : qemu-kvm vulnerabilities (USN-1145-1)

high Nessus Plugin ID 55108

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected qemu-kvm, qemu-kvm-extras and / or qemu-kvm-extras-static packages.
