|Bugzilla:||651183: CVE-2010-3879 CVE-2011-0541 CVE-2011-0542 CVE-2011-0543 fuse: unprivileged user can unmount arbitrary locations via symlink attack|
The MITRE CVE dictionary describes this issue as:
fusermount in fuse 2.8.5 and earlier does not perform a chdir to / before performing a mount or umount, which allows local users to unmount arbitrary directories via unspecified vectors.
The Red Hat Security Response Team has rated this issue as having low security impact. On Red Hat Enterprise Linux 5 and 6, a user must be a member of the 'fuse' group in order to use FUSE. Due to the risks associated with fixing this bug on Red Hat Enterprise Linux 5, and because of the group restrictions in place, we currently have no plans to fix this flaw in Red Hat Enterprise Linux 5.
