Description Eugene Teo (Security Response) 2011-06-19 21:48:45 EDT
A malicious user or buggy application can inject code and trigger an infinite loop in inet_diag_bc_audit()

Also make sure each instruction is aligned on 4 bytes boundary, to avoid unaligned accesses.

Statement:

This issue affects the Linux kernel as shipped with Red Hat Enterprise Linux 4,
5, 6, and Red Hat Enterprise MRG. Red Hat Enterprise Linux 4 is now in
Production 3 of the maintenance life-cycle, https://access.redhat.com/support/policy/updates/errata/, therefore the fix for this issue is not currently planned to be included in the future updates. This has been addressed in Red Hat Enterprise Linux 5, 6, and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0927.html, https://rhn.redhat.com/errata/RHSA-2011-1189.html and https://rhn.redhat.com/errata/RHSA-2011-1253.html.
