Vendor Statements (disclaimer)

Official Statement from Red Hat (11/20/2009)

Not vulnerable. This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 3, 4, and Red Hat Enterprise MRG as KVM (Kernel-based Virtual Machine) is only supported in Red Hat Enterprise Linux 5. Red Hat Enterprise Linux 5 is not vulnerable to this issue because it does not include the change that introduced this buffer overflow vulnerability.
