https://notcve.org/view.php?id=CVE-2011-0543
Certain legacy functionality in fusermount in fuse 2.8.5 and earlier, when util-linux does not support the --no-canonicalize option, allows local users to bypass intended access restrictions and unmount arbitrary directories via a symlink attack. Cierta funcionalidad en Fusermount en fuse v2.8.5 y anteriores, cuando util-linux no es compatible con la opción --no-canonicalize, permite a usuarios locales eludir restricciones de acceso y desmontar directorios de su elección mediante un ataque de enlaces simbólicos. • http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse%3Ba=commit%3Bh=cbd3a2a84068aae6e3fe32939d88470d712dbf47 http://lists.opensuse.org/opensuse-security-announce/2011-04/msg00000.html http://www.openwall.com/lists/oss-security/2011/02/02/2 http://www.openwall.com/lists/oss-security/2011/02/03/5 http://www.openwall.com/lists/oss-security/2011/02/08/4 https://access.redhat.com/security/cve/CVE-2011-0543 https://bugzilla.redhat.com/show_bug.cgi?id=651183 • CWE-264: Permissions, Privileges, and Access Controls •
