RHSA-2015:0383 - Moderate: ppc64-diag security, bug fix, and enhancement update

Synopsis

Moderate: ppc64-diag security, bug fix, and enhancement update

Type/Severity

Security Advisory Moderate

Topic

Updated ppc64-diag packages that fix two security issues, 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 Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

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 including support for hot plugging of QEMU PCI devices. (BZ#1088493, BZ#1084062)

This update also fixes the following bugs:

  • Prior to this update, the rtas_errd daemon was not started by default on system boot. With this update, rtas_errd has been modified to start automatically by default. (BZ#1170146)

  • Previously, the /var/log/dump file was not automatically created when installing the ppc64-diag package. This bug has been fixed, and /var/log/dump is now created at package install time as expected. (BZ#1175808)

In addition, this update adds the following enhancement:

  • This update adds support for building the ppc64-diag packages on the little-endian variant of IBM Power Systems platform architecture. (BZ#1124007)

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