Red Hat Security Advisory

 

Synopsis: Moderate: sos security and bug fix update

Advisory ID: RHSA-2016:0152-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0152.html

Issue date: 2016-02-09

CVE Names: CVE-2015-7529

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

 

1. Summary:

 

An updated sos package that fixes one security issue and one bug is now

available for Red Hat Enterprise Linux 6.

 

Red Hat Product Security has rated this update as having Moderate 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 Desktop (v. 6) - noarch

Red Hat Enterprise Linux HPC Node (v. 6) - noarch

Red Hat Enterprise Linux Server (v. 6) - noarch

Red Hat Enterprise Linux Workstation (v. 6) - noarch

 

3. Description:

 

The sos package contains a set of tools that gather information from system

hardware, logs and configuration files. The information can then be used

for diagnostic purposes and debugging.

 

An insecure temporary file use flaw was found in the way sos created

certain sosreport files. A local attacker could possibly use this flaw

to perform a symbolic link attack to reveal the contents of sosreport

files, or in some cases modify arbitrary files and escalate their

privileges on the system. (CVE-2015-7529)

 

This issue was discovered by Mateusz Guzik of Red Hat.

 

This update also fixes the following bug:

 

* Previously, when the hpasm plug-in ran the "hpasmcli" command in a Python

Popen constructor or a system pipeline, the command would hang and

eventually time out after 300 seconds. Sos was forced to wait for the time

out to finish, unnecessarily prolonging its run time. With this update, the

timeout of the "hpasmcli" command has been set to 0, eliminating the delay

and speeding up sos completion time. (BZ#1291828)

 

All sos users are advised to upgrade to this updated package, which

contains backported patches to correct these issues.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.
