Debian DLA-1002-1 : smb4k security update

high Nessus Plugin ID 101033

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Sebastian Krahmer from SUSE discovered that smb4k, a Samba (SMB) share advanced browser, contains a logic flaw in which the mount helper binary does not properly verify the mount command it is being asked to run.

This allows local users to call any other binary as root.

The issue is resolved by backporting version 1.2.1-2 from Debian 9 'Stretch'.

For Debian 7 'Wheezy', these problems have been fixed in version 1.2.1-2~deb7u1.

We recommend that you upgrade your smb4k packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected smb4k package.
