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.

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.
