Comment 4 Eugene Teo (Security Response) 2011-04-21 00:49:47 UTC

Statement:

The Linux kernel as shipped with Red Hat Enterprise Linux 3, 4 and 5 did not
include support for the CAN protocol, and therefore are not affected by this
issue. This has been addressed in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0836.html, and https://rhn.redhat.com/errata/RHSA-2011-1253.html.

Comment 5 Dave Jones 2011-04-21 01:01:23 UTC

note that the two patches in comment 1 and comment 2 address two separate issues in the same protocol.  Same bug, different code paths.
