Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for fuse fixes the following issues :

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)

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

Solution

To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or 'zypper patch'.

Alternatively you can run the command listed for your product :

SUSE Linux Enterprise Module for Basesystem 15:zypper in -t patch SUSE-SLE-Module-Basesystem-15-2018-2340=1
