Synopsis
========
A vulnerability in NTFS-3G allows local users to gain root privileges.
Background
==========
NTFS-3G is a stable, full-featured, read-write NTFS driver for various
operating systems.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-fs/ntfs3g < 2016.2.22-r2 >= 2016.2.22-r2
Description
===========
The NTFS-3G driver does not properly clear environment variables before
invoking mount or umount.
This flaw is similar to the vulnerability described in "GLSA-201701-19"
and "GLSA-201603-04" referenced below but is now implemented in the
NTFS-3G driver itself.
Impact
======
A local user could gain root privileges.
Workaround
==========
There is no known workaround at this time. However, on Gentoo when the
"suid" USE flag is not set (which is the default) an attacker cannot
exploit the flaw.
Resolution
==========
All NTFS-3G users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-fs/ntfs3g-2016.2.22-r2"
