NVD Description

Note: Versions mentioned in the description apply only to the upstream hylafaxplus package and not the hylafaxplus package as distributed by Alpine. See How to fix? for Alpine:3.11 relevant fixed versions and status.

In HylaFAX+ through 7.0.2 and HylaFAX Enterprise, the faxsetup utility calls chown on files in user-owned directories. By winning a race, a local attacker could use this to escalate his privileges to root.
