CVE-2010-3879

Published: 3 December 2010

FUSE, possibly 2.8.5 and earlier, allows local users to create mtab entries with arbitrary pathnames, and consequently unmount any filesystem, via a symlink attack on the parent directory of the mountpoint of a FUSE filesystem, a different vulnerability than CVE-2010-0789.
