USN-3463-1: Werkzeug vulnerability

25 October 2017

Werkzeug could be made to run arbitrary code if it opened a specially crafted file.




It was discovered that Werkzeug did not properly handle certain
web scripts. A remote attacker could use this to inject arbitrary
code via a field that contains an exception message.

Update instructions

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

Ubuntu 16.04
Ubuntu 14.04

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