RHEL 6 : sos (RHSA-2016:0152)

high Nessus Plugin ID 88675

Synopsis

The remote Red Hat host is missing a security update for sos.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2016:0152 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL sos package based on the guidance in RHSA-2016:0152.
