Title
MaterialX's unchecked nodeGraph->getOutput return is vulnerable to NULL Pointer Dereference
Summary
MaterialX is an open standard for the exchange of rich material and look-development content across applications and renderers. In version 1.39.2, when parsing shader nodes in a MTLX file, the MaterialXCore code accesses a potentially null pointer, which can lead to crashes with maliciously crafted files. An attacker could intentionally crash a target program that uses OpenEXR by sending a malicious MTLX file. This is fixed in version 1.39.3.

Title
Junos OS and Junos OS Evolved: When a static route points to a reject next-hop and a gNMI query for this route is processed, RPD crashes
Summary
A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause impact to the availability of the device.
When static route points to a reject next hop and a gNMI query is processed for that static route, rpd crashes and restarts.
This issue affects:
Junos OS: * all versions before 21.2R3-S9,
* 21.4 versions before 21.4R3-S10,
* 22.2 versions before 22.2R3-S6,
* 22.4 versions before 22.4R3-S6,
* 23.2 versions before 23.2R2-S3,
* 23.4 versions before 23.4R2-S4,
* 24.2 versions before 24.2R1-S2, 24.2R2;
Junos OS Evolved:
* all versions before 22.4R3-S7-EVO,
* 23.2-EVO
versions before 23.2R2-S3-EVO,
* 23.4-EVO versions before 23.4R2-S4-EVO,
* 24.2-EVO versions before 24.2R2-EVO.

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