openSUSE Security Update : fuse (openSUSE-2018-1225)

high Nessus Plugin ID 118340

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

This update for fuse fixes the following security issue :

 - CVE-2018-10906: fusermount was vulnerable to a restriction bypass when SELinux is active. This allowed non-root users to mount a FUSE file system with the 'allow_other' mount option regardless of whether 'user_allow_other' is set in the fuse configuration. An attacker may use this flaw to mount a FUSE file system, accessible by other users, and trick them into accessing files on that file system, possibly causing Denial of Service or other unspecified effects (bsc#1101797)

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

Solution

Update the affected fuse packages.
