"An update for sos-collector is now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

sos-collector is a utility that gathers sosreports from multi-node
environments. sos-collector facilitates data collection for support
cases and it can be run from either a node or from an administrator's
local workstation that has network access to the environment.

The following packages have been upgraded to a later upstream version:
sos-collector (1.5). (BZ#1644776)

Security Fix(es) :

* sos-collector: incorrect permissions set on newly created files
(CVE-2018-14650)

For more details about the security issue(s), including the impact, a
CVSS score, and other related information, refer to the CVE page(s)
listed in the References section.

This issue was discovered by Riccardo Schirone (Red Hat Product
Security)."
