A vulnerability in NTFS-3G allows local users to gain root privileges.
|Package||sys-fs/ntfs3g on all architectures|
|Affected versions||< 2016.2.22-r2|
|Unaffected versions||>= 2016.2.22-r2|
NTFS-3G is a stable, full-featured, read-write NTFS driver for various operating systems.
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.
A local user could gain root privileges.
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.
All NTFS-3G users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-fs/ntfs3g-2016.2.22-r2"
