USN-2986-1: dosfstools vulnerabilities

31 May 2016

dosfstools could be made to crash or run programs if it processed a specially crafted filesystem.

Releases

Packages

  • dosfstools - utilities for making and checking MS-DOS FAT filesystems

Details

Hanno Böck discovered that dosfstools incorrectly handled certain malformed
filesystems. A local attacker could use this issue to cause dosfstools to
crash, resulting in a denial of service, or possibly execute arbitrary
code.

Update instructions

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

Ubuntu 16.04
Ubuntu 15.10
Ubuntu 14.04
Ubuntu 12.04

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