An issue was discovered in Mattermost Server before 5.21.0. Socket read operations are not appropriately restricted, which allows attackers to cause a denial of service, aka MMSA-2020-0005.
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
