CVE-2019-17266 libsoup vulnerability
Title: libsoup vulnerability
Summary: libsoup could be made to crash if it received specially crafted network
traffic.
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.
Instructions: In general, a standard system update will make all the necessary changes.
