fusermount in FUSE before 2.9.3-15 does not properly clear the environment before invoking (1) mount or (2) umount as root, which allows local users to write to arbitrary files via a crafted LIBMOUNT_MTAB environment variable that is used by mount's debugging feature.

SUMMARY = "Implementation of a fully functional filesystem in a userspace program"

DESCRIPTION = "FUSE (Filesystem in Userspace) is a simple interface for userspace \
|
|
programs to export a virtual filesystem to the Linux kernel. FUSE \
|
|
also aims to provide a secure method for non privileged users to \
|
|
create and mount their own filesystem implementations. \
