   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)
