USN-4170-3: Whoopsie regression
5 November 2019

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

  o Ubuntu 19.10
  o Ubuntu 19.04
  o Ubuntu 18.04 LTS
  o Ubuntu 16.04 LTS


USN-4170-2 caused a regression in Whoopsie

Software Description

  o whoopsie - Ubuntu error tracker submission


USN-4170-1 fixed a vulnerability in Whoopsie and USN-4170-2 fixed a subsequent
regression. That update was incomplete and could still result in Whoopsie
potentially crashing when uploading crash reports on some architectures. This
update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

Kevin Backhouse discovered Whoopsie incorrectly handled very large crash
reports. A local attacker could possibly use this issue to cause a denial of
service, expose sensitive information or execute code as the whoopsie user.
