The remote host is affected by the vulnerability described in GLSA-201702-10 (NTFS-3G: Privilege escalation)
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.
