CVE-2018-19046 is a vulnerability of currently unknown severity. keepalived 2.0.8 didn't check for existing plain files when writing data to a temporary file upon a call to PrintData or PrintStats. If a local attacker had previously created a file with the expected name (e.g., /tmp/keepalived.data or /tmp/keepalived.stats), with read access for the attacker and write access for the keepalived process, then this potentially leaked sensitive information.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
