CVE-2011-0463 [LOW] Linux kernel (OMAP4) vulnerabilities
Title: Linux kernel (OMAP4) vulnerabilities
Summary: Multiple kernel flaws have been fixed.
Goldwyn Rodrigues discovered that the OCFS2 filesystem did not correctly
clear memory when writing certain file holes. A local attacker could
exploit this to read uninitialized data from the disk, leading to a loss of
privacy. (CVE-2011-0463)
Timo Warns discovered that the LDM disk partition handling code did not
correctly handle certain values. By inserting a specially crafted disk
device, a local attacker could exploit this to gain root privileges.
(CVE-2011-1017)
It was discovered that the /proc filesystem did not correctly handle
permission changes when programs executed. A local attacker could hold open
files to examine details about programs running with higher privileges,

CVE-2011-1182 [LOW] kernel signal spoofing issue
kernel signal spoofing issue
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.
