USN-4152-1: libsoup vulnerability
9 October 2019
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 19.04
o Ubuntu 18.04 LTS
libsoup could be made to crash if it received specially crafted network
o 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.
The problem can be corrected by updating your system to the following package
libsoup2.4-1 - 2.66.1-1ubuntu0.1
Ubuntu 18.04 LTS
libsoup2.4-1 - 2.62.1-1ubuntu0.4
To update your system, please follow these instructions: https://
In general, a standard system update will make all the necessary changes.
