Ubuntu 10.04 LTS / 10.10 / 11.04 / 11.10 : qemu-kvm vulnerability (USN-1339-1)
High Nessus Plugin ID 57663
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionNicolae Mogoreanu discovered that QEMU did not properly verify legacy mode packets in the e1000 network driver. A remote attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
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.
SolutionUpdate the affected qemu-kvm, qemu-kvm-extras and / or qemu-kvm-extras-static packages.
