CVE-2018-19046 (opens in a new tab)How to fix?
Upgrade Alpine:3.20 keepalived to version 2.0.11-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream keepalived package and not the keepalived package as distributed by Alpine.
See How to fix? for Alpine:3.20 relevant fixed versions and status.
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.
