Title
BIG-IP Advanced WAF and ASM vulnerability
Summary
When a BIG-IP Advanced WAF or BIG-IP ASM policy with a Request Body Handling option is attached to a virtual server, undisclosed requests can cause the BD process to terminate. The condition results from setting the Request Body Handling option in the Header-Based Content Profile for an Allowed URL with "Apply value and content signatures and detect threat campaigns." Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

Title
Parsing JSON serialized payload without protected field can lead to segfault
Summary
jwx is a Go module implementing various JWx (JWA/JWE/JWK/JWS/JWT, otherwise known as JOSE) technologies. Calling `jws.Parse` with a JSON serialized payload where the `signature` field is present while `protected` is absent can lead to a nil pointer dereference. The vulnerability can be used to crash/DOS a system doing JWS verification. This vulnerability has been patched in versions 2.0.19 and 1.2.28.

Title
Junos OS Evolved: ACX7024, ACX7100-32C and ACX7100-48L: Traffic stops when a specific IPv4 UDP packet is received by the RE
Summary
A NULL Pointer Dereference vulnerability in Juniper Networks Junos OS Evolved on ACX7024, ACX7100-32C and ACX7100-48L allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
If a specific IPv4 UDP packet is received and sent to the Routing Engine (RE) packetio crashes and restarts which causes a momentary traffic interruption. Continued receipt of such packets will lead to a sustained DoS.
This issue does not happen with IPv6 packets.
This issue affects Juniper Networks Junos OS Evolved on ACX7024, ACX7100-32C and ACX7100-48L:
* 21.4-EVO versions earlier than 21.4R3-S6-EVO;
* 22.1-EVO versions earlier than 22.1R3-S5-EVO;
* 22.2-EVO versions earlier than 22.2R2-S1-EVO, 22.2R3-EVO;
* 22.3-EVO versions earlier than 22.3R2-EVO.
This issue does not affect Juniper Networks Junos OS Evolved versions earlier than 21.4R1-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.
