USN-3914-1: NTFS-3G vulnerability

21 March 2019

ntfs-3g vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 18.10
  • Ubuntu 18.04 LTS
  • Ubuntu 16.04 LTS


NTFS-3G could be made to crash or potentially run programs as an administrator if executed with specially crafted arguments.

Software Description

  • ntfs-3g - read/write NTFS driver for FUSE


A heap buffer overflow was discovered in NTFS-3G when executing it with a relative mount point path that is too long. A local attacker could potentially exploit this to execute arbitrary code as the administrator.

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.10
