NTFS-3G: Privilege escalation — GLSA 201701-19

A vulnerability in NTFS-3G allows local users to gain root privileges.

Affected packages

sys-fs/ntfs3g on all architectures
Affected versions < 2016.2.22
Unaffected versions >= 2016.2.22

Background

NTFS-3G is a stable, full-featured, read-write NTFS driver for various operating systems.

Description

NTFS-3G is affected by the same vulnerability as reported in “GLSA 201603-04” when the bundled fuse-lite implementation is used.

Impact

A local user could gain root privileges.

Workaround

There is no known workaround at this time. However, on Gentoo when the “external-fuse” USE flag is set or the “suid” USE flag is not set then NTFS-3G is not affected. Both of these cases are the default configuration.

Resolution

All NTFS-3G users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=sys-fs/ntfs3g-2016.2.22"
