Synopsis

The remote CentOS host is missing a security update.

Description

An updated sos package that fixes one security issue and one bug is now available for Red Hat Enterprise Linux 7.

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.

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.

Solution

Update the affected sos package.
