ExifReader is vulnerable to denial of service via unbounded decompression of image metadata

Impact Versions of ExifReader from 4.20.0 through 4.38.1 do not bound the size of decompressed metadata blocks. When a caller invokes the asynchronous API e.g. ExifReader.loadfile or ExifReader.loadbuffer, async: true on an attacker-supplied image, a small compressed chunk in the file can expand ...
