Synopsis

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

Description

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2016:0188 advisory.

The sos package contains a set of utilities 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, the sosreport tool was not collecting the /var/lib/ceph and /var/run/ceph directories when run with the ceph plug-in enabled, causing the generated sosreport archive to miss vital troubleshooting information about ceph. With this update, the ceph plug-in for sosreport collects these directories, and the generated report contains more useful information.
(BZ#1291347)

All users of sos 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-2016:0188.
