GLSA-201702-10 : NTFS-3G: Privilege escalation

high Nessus Plugin ID 97253

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

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.

Solution

All NTFS-3G users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=sys-fs/ntfs3g-2016.2.22-r2'
