CVE-2018-14650 (GCVE-0-2018-14650)

Vulnerability from cvelistv5 – Published: 2018-09-27 20:00 – Updated: 2024-08-05 09:38

Summary

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.

Severity
