An update that fixes one vulnerability is now available.
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)

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