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)
