Statement
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5.
Red Hat Enterprise Linux 7 and Red Hat Enterprise MRG 2 only support 64-bit architectures. Since exploiting this issue on 64-bit platforms is not feasible given the amount of input data that is necessary to trigger the integer overflow, we are currently not planning planning to fix this issue in Red Hat Enterprise Linux 7 and Red Hat Enterprise MRG 2.
