hylafaxplus: Multiple vulnerabilities (CVE-2020-15396, CVE-2020-15397)
CVE-2020-15396: Race condition in faxsetup utility could lead to privileges escalation
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.
CVE-2020-15397: Unsafe handling of user-writable directories could lead to privileged code execution
HylaFAX+ through 7.0.2 and HylaFAX Enterprise have scripts that execute binaries from directories writable by unprivileged users (e.g., locations under /var/spool/hylafax that are writable by the uucp account). This allows these users to execute code in the context of the user calling these binaries (often root).
