Official Description

Bio-Formats versions up to and including 8.3.0 perform unsafe Java deserialization of attacker-controlled memoization cache files (.bfmemo) during image processing. The loci.formats.Memoizer class automatically loads and deserializes memo files associated with images without validation, integrity checks, or trust enforcement. An attacker who can supply a crafted .bfmemo file alongside an image can trigger deserialization of untrusted data, which may result in denial of service, logic manipulation, or potentially remote code execution in environments where suitable gadget chains are present on the classpath.

Attack Vector Analysis — CITED Relevance

An attacker can exploit this vulnerability by supplying a crafted .bfmemo file alongside an image. The loci.formats.Memoizer class in Bio-Formats automatically loads and deserializes these files, which can lead to remote code execution if the attacker crafts the file to include malicious serialized objects.
