libsoup2.4 vulnerability
==========================================================================

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

- Ubuntu 19.04
- Ubuntu 18.04 LTS

Summary:

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

Software Description:
- 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.

Update instructions:

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

Ubuntu 19.04:
  libsoup2.4-1                    2.66.1-1ubuntu0.1

Ubuntu 18.04 LTS:
  libsoup2.4-1                    2.62.1-1ubuntu0.4

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