GHSA-W833-PX7J-Q64C
Vulnerability from github – Published: 2023-10-19 12:30 – Updated: 2024-04-04 08:47The Motorola MTM5000 series firmwares lack pointer validation on arguments passed to trusted execution environment (TEE) modules. Two modules are used, one responsible for KVL key management and the other for TETRA cryptographic functionality. In both modules, an adversary with non-secure supervisor level code execution can exploit the issue in order to gain secure supervisor code execution within the TEE. This constitutes a full break of the TEE module, exposing the device key as well as any TETRA cryptographic keys and the confidential TETRA cryptographic primitives.

GHSA-WG63-8XJW-5WVX
Vulnerability from github – Published: 2022-06-17 00:01 – Updated: 2022-06-28 00:00In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of service.

Mitigation
Only call matching memory management functions. Do not mix and match routines. For example, when you allocate a buffer with malloc(), dispose of the original pointer with free().
Mitigation
When programming in C++, consider using smart pointers provided by the boost library to help correctly and consistently manage memory.
Mitigation MIT-4.6
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, glibc in Linux provides protection against free of invalid pointers.
Mitigation
Use a language that provides abstractions for memory allocation and deallocation.
