Detail

Synopsis

A vulnerability in Smb4K could allow local attackers to execute commands as root.

Background

Smb4K is a SMB/CIFS (Windows) share browser for KDE.

Description

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.

Resolution

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