33
34 Description
35 ===========
36
37 Smb4k contains a logic flaw in which mount helper binary does not
38 properly verify the mount command it is being asked to run.
39
40 Impact
41 ======
42
43 A local user can execute commands with the root privilege due to the
44 mount helper being installed as suid.

49 There is no known workaround at this time.
50
51 Resolution
52 ==========
53
54 All Smb4K users should upgrade to the latest version:
55
56 # emerge --sync
57 # emerge --ask --oneshot --verbose ">=net-misc/smb4k-1.2.3-r1:4 "
