Detailed vulnerability description
The vulnerability allows a remote attacker to bypass security restrictions on the target system.
The weakness exists due to insufficient access and privileges controls. A remote attacker can mount a FUSE file system with the 'allow_other' mount option regardless of whether 'user_allow_other' is set in the fuse configuration when SELinux is active, trick them into accessing files on that file system, bypass security restrictions and possibly cause the service to crash.
