CVE-2010-3879

Publication date 3 December 2010

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
