CVE-2017-8849 [HIGH] CVE-2017-8849 smb4k: unauthorized local command execution as root
CVE-2017-8849 smb4k: unauthorized local command execution as root
Smb4k contains a logic flaw in which mount helper binary does not properly verify the mount command it is being asked to run. This allows calling any other binary as root since the mount helper is typically installed as suid.
Affected versions: smb4k Sergio, feel free to update to 1.2.3 if you think there's no regression in
> new version.
