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

- Ubuntu 19.04 - Ubuntu 18.04 LTS


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

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


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.
