Description Adam Mariš 2016-11-11 08:52:22 UTC 
Apache Tika wraps the jmatio parser (https://github.com/gradusnikov/jmatio) to handle MATLAB files.  The parser uses native deserialization on serialized Java objects embedded in MATLAB files. A malicious user could inject arbitrary code into a MATLAB file that would be executed when the object is deserialized.

Versions Affected: 1.6-1.13 

Mitigation: Turn off MATLAB file parsing or upgrade to Tika 1.14
