CVE-2020-8032

Local root escalation via insecure temporary file

Published Feb 25, 2021 · Updated Sep 16, 2024

Insecure temporary file handling in openSUSE Factory cyrus-sasl through 2.1.27-4.2 allows local users to escalate to root. The packaging used /tmp for update scripts in a way that permitted unsafe temporary-file manipulation; the fix moves scripts to /var/adm/update-scripts and cleans them up. Exploitation requires local access, and successful abuse can grant root privileges with resulting confidentiality, integrity, and availability impact.
