YASM v1.3.0 - Heap Overflow in handle_dot_label Function

Title source: llm

Description

YASM v1.3.0 was discovered to contain a heap overflow via the function handle_dot_label at /nasm/nasm-token.re. Note: This has been disputed by third parties who argue this is a bug and not a security issue because yasm is a standalone program not designed to run untrusted code.
