==========================================================================

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

- - Ubuntu 18.04 LTS
- - Ubuntu 17.10
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS

Summary:

libsoup could be made to crash if it received a specially crafted
input.

Software Description:
- - libsoup2.4: HTTP client/server library for GNOME

Details:

It was discovered that libsoup incorrectly handled certain cookie
requests. An attacker could possibly use this to cause a denial of
service.

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

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

Ubuntu 17.10:
