high Nessus Plugin ID 100446

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201705-14 (Smb4K: Arbitrary 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.
 Impact :

 A local user can execute commands with the root privilege due to the mount helper being installed as suid.
 Workaround :

 There is no known workaround at this time.

Solution

All Smb4K users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/smb4k-1.2.3-r1:4'
