mvapich2 component
The mvapich2 packages use the GNU Autotools set of tools (autoconf, automake, and libtool) to process its configuration. Features included in version 1.12 and later are required, but are not available in Red Hat Enterprise Linux 6.6 and earlier. As a consequence, rebuilding mvapich2 fails with earlier versions of GNU Autotools. To work around this problem, uninstall the autoconf, automake, and libtool packages, rebuild mvapich2, and then reinstall GNU Autotools.
freeipmi component, BZ#1020650
Under certain circumstances, the IPMI service is not started and the ipmi_devintf kernel module that provides the device node interface is not loaded. As a consequence, some hardware could reboot unexpectedly after installation before the first intentional reboot. To work around this problem, run the following commands as root:
chkconfig --level 345 ipmi on
service ipmi restart
service bmc-watchdog condrestart
Alternatively, log in as root, create the /etc/modprobe.d/watchdog-reboot-workaround.conf file, and include the following three aliases:
alias acpi:IPI000*:* ipmi_si
alias acpi:IPI000*:* ipmi_devintf
alias acpi:IPI000*:* ipmi_msghandler
ssh-keygen component
The following example in the description of the -V option in the ssh-keygen(1) manual page is incorrect:
“-4w:+4w” (valid from four weeks ago to four weeks from now)
If you set a date range in this format, the certificate is valid from four weeks ago until now.
perl-WWW-curl component
Attempting to access the CURLINFO_PRIVATE value can cause curl to terminate unexpectedly with a segmentation fault.
freerpd component, BZ#988277
The ALSA plug-in is not supported in Red Hat Enterprise Linux 6. Instead of the ALSA plug-in, use the pulseaudio plug-in. To enable it, use the --plugin rpdsnd option with the xfreerdp command without specifying which plug-in should be used; the pulseaudio plug-in will be used automatically in this case.
coolkey component, BZ#906537
Personal Identity Verification (PIV) Endpoint Cards which support both CAC and PIV interfaces might not work with the latest coolkey update; some signature operations like PKINIT can fail. To work around this problem, downgrade coolkey to the version shipped with Red Hat Enterprise Linux 6.3.
libreport component
Even if the stored credentials are used , the report-gtk utility can report the following error message:
Wrong settings detected for Red Hat Customer Support [..]
To work around this problem, close the dialog window; the Login=<rhn-user> and Password=<rhn-password> credentials in the /etc/libreport/plugins/rhtsupport.conf will be used in the same way they are used by report-rhtsupport.

vlock component
When a user password is used to lock a console with vlock, the console can only be unlocked with the user password, not the root password. That is, even if the first inserted password is incorrect, and the user is prompted to provide the root password, entering the root password fails with an error message.
libreoffice component
Libreoffice contains a number of harmless files used for testing purposes. However, on Microsoft Windows system, these files can trigger false positive alerts on various anti-virus software, such as Microsoft Security Essentials. For example, the alerts can be triggered when scanning the Red Hat Enterprise Linux 6 ISO file.
gnome-power-manager component
When the computer runs on battery, custom brightness level is not remembered and restored if power saving features like "dim display when idle" or "reduce backlight brightness when idle" are enabled.
rsyslog component
rsyslog does not reload its configuration after a SIGHUP signal is issued. To reload the configuration, the rsyslog daemon needs to be restarted:
~]# service rsyslog restart
