Details

USN-3914-1 fixed vulnerabilities in NTFS-3G. As an additional hardening
measure, this update removes the setuid bit from the ntfs-3g binary.

A heap buffer overflow was discovered in NTFS-3G when executing it with a
relative mount point path that is too long. A local attacker could
potentially exploit this to execute arbitrary code as the administrator.
