What is CVE-2018-10906?
CVE-2018-10906 is a medium-severity vulnerability in Debian Debian Linux, published on 24 Jul 2018. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
In fuse before versions 2.9.8 and 3.x before 3.2.5, fusermount is vulnerable to a restriction bypass when SELinux is active. This allows 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.
