Package        : fuse
CVE ID         : CVE-2018-10906
Debian Bug     : 904439

Jann Horn discovered that FUSE, a Filesystem in USErspace, allows the
bypass of the 'user_allow_other' restriction when SELinux is active
(including in permissive mode). A local user can take advantage of this
flaw in the fusermount utility to bypass the system configuration and
mount a FUSE filesystem with the 'allow_other' mount option.

For the stable distribution (stretch), this problem has been fixed in
version 2.9.7-1+deb9u1.

We recommend that you upgrade your fuse packages.
