{"id":"UBUNTU-CVE-2018-10906","details":"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.","modified":"2026-01-30T01:35:47.466966Z","published":"2018-07-24T20:29:00Z","related":["USN-5326-1"],"upstream":["CVE-2018-10906"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-10906"},{"type":"REPORT","url":"https://github.com/libfuse/libfuse/pull/268"},{"type":"REPORT","url":"https://sourceforge.net/p/fuse/mailman/message/36374753/"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5326-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-10906"}],"affected":[{"package":{"name":"fuse","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/fuse@2.9.2-4ubuntu4.14.04.1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.9.2-4ubuntu3","2.9.2-4ubuntu4","2.9.2-4ubuntu4.14.04.1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.9.2-4ubuntu4.14.04.1","binary_name":"fuse"},{"binary_version":"2.9.2-4ubuntu4.14.04.1","binary_name":"libfuse-dev"},{"binary_version":"2.9.2-4ubuntu4.14.04.1","binary_name":"libfuse2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-10906.json"}},{"package":{"name":"fuse","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/fuse@2.9.4-1ubuntu3.1+esm1?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.9.4-1ubuntu3.1+esm1"}]}],"versions":["2.9.4-1ubuntu1","2.9.4-1ubuntu2","2.9.4-1ubuntu3","2.9.4-1ubuntu3.1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.9.4-1ubuntu3.1+esm1","binary_name":"fuse"},{"binary_version":"2.9.4-1ubuntu3.1+esm1","binary_name":"libfuse-dev"},{"binary_version":"2.9.4-1ubuntu3.1+esm1","binary_name":"libfuse2"}],"availability":"Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-10906.json"}},{"package":{"name":"fuse","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/fuse@2.9.7-1ubuntu1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.9.7-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.9.7-1ubuntu1","binary_name":"fuse"},{"binary_version":"2.9.7-1ubuntu1","binary_name":"libfuse-dev"},{"binary_version":"2.9.7-1ubuntu1","binary_name":"libfuse2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-10906.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"low"}]}
