Ubuntu 10.04 LTS / 10.10 / 11.04 / 11.10 : qemu-kvm vulnerability (USN-1339-1)

Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

Nicolae 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.

Solution :

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

Risk factor :

High / CVSS Base Score : 7.4
(CVSS2#AV:A/AC:M/Au:S/C:C/I:C/A:C)
CVSS Temporal Score : 5.5
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
