An issue was discovered in Pillow before 8.2.0. For BLP data, BlpImagePlugin did not properly check that reads (after jumping to file offsets) returned data. This could lead to a DoS where the decoder could be run a large number of times on empty data.
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
