N/A - USN-3914-2

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

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

A hardening measure was added to NTFS-3G.

Software Description: - ntfs-3g: read/write NTFS driver for FUSE

Details:

USN-3914-1 fixed vulnerabilities in NTFS-3G. As an additional hardening measure, this update removes the setuid bit from the ntfs-3g binary.

Original advisory details:

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.

Update instructions:

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

Ubuntu 18.10:
ntfs-3g 1:2017.3.23-2ubuntu0.18.10.2

Ubuntu 18.04 LTS:
ntfs-3g 1:2017.3.23-2ubuntu0.18.04.2

Ubuntu 16.04 LTS:
ntfs-3g 1:2015.3.14AR.1-1ubuntu0.3

In general, a standard system update will make all the necessary changes.
