sosreport in SoS 3.x allows local users to obtain sensitive information from sosreport files or gain privileges via a symlink attack on an archive file in a temporary directory, as demonstrated by sosreport-$hostname-$date.tar in /tmp/sosreport-$hostname-$date.

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.

Security fix for CVE-2015-7529

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 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.

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.

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.
