Vulnerable:

Yes

In the Debian bugtracking system: Bug 904439.

More information:

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.
