CVE-2018-14650 (opens in a new tab)How to fix?
Upgrade RHEL:7 sos-collector to version 0:1.5-3.el7_6 or higher.
This issue was patched in RHSA-2018:3663.
NVD Description
Note: Versions mentioned in the description apply only to the upstream sos-collector package and not the sos-collector package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
It was discovered that sos-collector does not properly set the default permissions of newly created files, making all files created by the tool readable by any local user. A local attacker may use this flaw by waiting for a legit user to run sos-collector and steal the collected data in the /var/tmp directory.
