Ubuntu Security Notice USN-3914-2
April 17, 2019
ntfs-3g update
==========================================================================
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.
