This can cause lead to the disclosure of information within some memory locations. (CVE-2019-11046)

 - An out-of-bounds READ error exists in parsing EXIF information from an image. An unauthenticated, remote attacker can exploit this and supply it iwth data that will cause it to read past the allocated buffer disclosing of information.
