9 October 2019

libsoup2.4 vulnerability
A security issue affects these releases of Ubuntu and its derivatives:

  o Ubuntu 19.04
  o Ubuntu 18.04 LTS

Summary

libsoup could be made to crash if it received specially crafted network
traffic.

Software Description

  o libsoup2.4 - HTTP client/server library for GNOME

Details

It was discovered that libsoup incorrectly handled parsing certain NTLM
messages. If a user or automated system were tricked into connecting to a
malicious server, a remote attacker could possibly use this issue to cause a
denial of service.
