Overview

dm-reverb is a Reverb is an efficient and easy-to-use data storage and transport system designed for machine learning research.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data due to the unpacking process of tensor proto of type VARIANT. An attacker can gain control of the Program Counter by inserting malicious streams into the server's database, which are then unpacked when the client calls SampleStream and any method on the unpacked object is called.

Details

Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.

Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.
