CVE-2011-1182

Description

From CVE.org

kernel/signal.c in the Linux kernel before 2.6.39 allows local users to spoof the uid and pid of a signal sender via a sigqueueinfo system call.

Statement

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 was addressed in Red Hat Enterprise Linux 5 and 6 via https://rhn.redhat.com/errata/RHSA-2011-0927.html and https://rhn.redhat.com/errata/RHSA-2011-1189.html. A future kernel update in Red Hat Enterprise MRG may address this flaw.
