Dist Redhat Esm H88
Rectifies a vulnerability within the Ubuntu system utilities, improving resilience with an update for optimized operation.
An updated sos package that fixes one security issue and one bug is now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

Summary

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.
