Title
TensorFlow has null dereference on ParallelConcat with XLA
Summary
TensorFlow is an open source machine learning platform. When running versions prior to 2.12.0 and 2.11.1 with XLA, `tf.raw_ops.ParallelConcat` segfaults with a nullptr dereference when given a parameter `shape` with rank that is not greater than zero. A fix is available in TensorFlow 2.12.0 and 2.11.1.

Summary
A NULL pointer dereference flaw was found in Libtiff's LZWDecode() function in the libtiff/tif_lzw.c file. This flaw allows a local attacker to craft specific input data that can cause the program to dereference a NULL pointer when decompressing a TIFF format file, resulting in a program crash or denial of service.
Severity

Mitigation ID: MIT-56

Phase: Implementation

Description:

  • 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

Phase: Requirements

Description:

  • Select a programming language that is not susceptible to these issues.
Mitigation

Phase: Implementation

Description:

  • Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation

Phase: Architecture and Design

Description:

  • 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

Phase: Implementation

Description:

  • Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
