(RHSA-2015:1320) Moderate: ppc64-diag security, bug fix and enhancement update

The ppc64-diag packages provide diagnostic tools for Linux on the 64-bit
PowerPC platforms. The platform diagnostics write events reported by the
firmware to the service log, provide automated responses to urgent events,
and notify system administrators or connected service frameworks about the
reported events.

Multiple insecure temporary file use flaws were found in the way the
ppc64-diag utility created certain temporary files. A local attacker could
possibly use either of these flaws to perform a symbolic link attack and
overwrite arbitrary files with the privileges of the user running
ppc64-diag, or obtain sensitive information from the temporary files.
(CVE-2014-4038, CVE-2014-4039)

The ppc64-diag packages have been upgraded to upstream version 2.6.7, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#1148142)

This update also fixes the following bugs:

• Previously, the “explain_syslog” and “syslog_to_svclog” commands failed
  with a “No such file or directory” error message. With this update, the
  ppc64-diag package specifies the location of the message_catalog directory
  correctly, which prevents the described error from occurring. (BZ#1139655)

• Prior to this update, the /var/lock/subsys/rtas_errd file was incorrectly
  labeled for SELinux as “system_u:object_r:var_lock_t:s0”. This update
  corrects the SELinux label to “system_u:object_r:rtas_errd_var_lock_t:s0”.
  (BZ#1131501)

Users of ppc64-diag are advised to upgrade to these updated packages, which
correct these issues and add these enhancements.
