CVE-2018-10906

Public on 2018-07-24
Modified on 2019-04-19
Description

A vulnerability was discovered in fuse. When SELinux is active, fusermount is vulnerable to a restriction bypass. 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.
