Title
Control iD iDSecure Unauthenticated Denial of Service
Summary
Control iD iDSecure versions prior to 4.8.3.0 are affected by an unauthenticated Denial of Service.
The /api/dguardintegration/dguardVersion endpoint dereferences DGuard integration login state that may be unset, raising an unhandled null reference exception. The exception is thrown from an asynchronous method that returns void, so it is not observed by a caller and can terminate the iDSecure process.

The identifier of the patch is 7322e9bc30cb282575a701c307851fd3d66fee68. It is suggested to upgrade the affected component."

Title
Sssd: sssd: local denial of service due to null pointer dereference in pam responder
Summary
A flaw was found in SSSD (System Security Services Daemon). A local attacker with privileges to connect to the PAM (Pluggable Authentication Modules) responder socket can send a specially crafted protocol request. If the `pam_app_services` configuration is enabled and the service item is omitted from the request, a NULL pointer dereference can occur. This vulnerability leads to a denial of service, causing the PAM responder to crash and disrupt authentication services.

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.
