critical Nessus Plugin ID 100499

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

This update for samba fixes the following issue :

- An unprivileged user with access to the samba server could cause smbd to load a specially crafted shared library, which then had the ability to execute arbitrary code on the server as 'root'. [CVE-2017-7494, bso#12780, bsc#1038231]

This update was imported from SUSE:SLE-12-SP1:Update project.

NOTE: This update is released in openSUSE Leap 42.1 after its official End Of Life only because of its severity and potential impact for users that have not migrated yet.

Please upgrade your openSUSE Leap 42.1 as soon as possible.

Solution
