USN-3914-2: NTFS-3G update

Releases

• Ubuntu 18.10
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• 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

• ntfs-3g - 1:2017.3.23-2ubuntu0.18.04.2

Ubuntu 16.04

• ntfs-3g - 1:2015.3.14AR.1-1ubuntu0.3

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