Title
Eclipse OMR: Null pointer dereference vulnerability
Summary
In Eclipse OMR, from the initial contribution to version 0.4.0, some OMR internal port library and utilities consumers of z/OS atoe functions do not check their return values for NULL memory pointers or for memory allocation failures. This can lead to NULL pointer dereference crashes. Beginning in version 0.5.0, internal OMR consumers of atoe functions handle NULL return values and memory allocation failures correctly.

Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Requirements
Select a programming language that is not susceptible to these issues.

Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
