CVE Names: CVE-2014-4040

=====================================================================

 

1. Summary:

 

Updated powerpc-utils packages that fix one security issue, several bugs,

and add various enhancements are now available for Red Hat Enterprise

Linux 7.

 

Red Hat Product Security has rated this update as having Low security

impact. A Common Vulnerability Scoring System (CVSS) base score, which

gives a detailed severity rating, is available from the CVE link in the

References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Server (v. 7) - ppc64

 

3. Description:

 

The powerpc-utils packages provide various utilities for the PowerPC

platform.

 

A flaw was found in the way the snap utility of powerpc-utils generated an

archive containing a configuration snapshot of a service. A local attacker

could obtain sensitive information from the generated archive such as plain

text passwords. (CVE-2014-4040)

 

The powerpc-utils packages have been upgraded to the upstream version

1.2.24, which provides a number of bug fixes and enhancements over the

previous version. (BZ#1088539, BZ#1167865, BZ#1161552)

 

This update also fixes the following bugs:

 

* Previously, the lsdevinfo command did not correctly process the path to

the device, which made the path unreadable in the console output of

lsdevinfo. With this update, lsdevinfo has been updated and the path is now

displayed correctly. (BZ#1079246)

 

* Previously, after migrating several Linux partitions, Resource Monitoring

and Control (RMC) was inactive and Machine Type, Model, and Serial number

(MTMS) were set incorrectly, so the subsequent validation operation failed.

This bug has been fixed, and validation is now successful after migration

and suspend. (BZ#1083221)

 

* Previously, when the drmgr tool attempted to remove the last CPU from the

system, drmgr became unresponsive or terminated unexpectedly. This bug has

been fixed, and drmgr no longer hangs or crashes in the described case.

(BZ#1152313)

 

* With this update, the drmgr utility has been fixed to correctly gather

Logical Memory Block (LMB) information while performing Mem Dynamic Logical

Partitioning (DLPAR) on little-endian varian of IBM Power Systems CPU

architecture as expected (BZ#1170856).

 

* Previously, the "ppc64_cpu --threads-per-core" command returned incorrect

data with the --smt option enabled. This bug has been fixed and "ppc64_cpu

- --threads-per-core" now reports correctly with enabled --smt. (BZ#1179263)

 

In addition, this update adds the following enhancements:

 

* This update adds support for the Red Hat Enterprise Linux for POWER,

little endian CPU architecture to the powerpc-utils package. (BZ#1124006)

 

* This update adds support for hot plugging of the qemu virtio device with

the drmgr command to the powerpc-utils package.(BZ#1083791)

 

* The deprecated snap tool has been removed from the powerpc-utils

packages. Its functionality has been integrated into the sosreport tool.

(BZ#1172087)

 

* With this update, a dependency on the perl-Data-Dumper package required

by the rtas_dump utility has been added to powerpc-utils packages.

(BZ#1175812)

 

Users of powerpc-utils are advised to upgrade to these updated packages,

which correct these issues and add these enhancements.
