CVE-2018-10906: Debian Linux

High severity, CVSS 7.8. EPSS: 1.4% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 8.0 only; version 9.0 only
• Fuse Project Fuse: before 2.9.8 (fixed in 2.9.8); from 3.0, before 3.2.5 (fixed in 3.2.5)
• Red Hat Enterprise Linux Desktop: version 7.0 only
• Red Hat Enterprise Linux Server: version 7.0 only
• Red Hat Enterprise Linux Workstation: version 7.0 only
