Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

SQL Injection: User-controlled password inputs are directly integrated into dynamic SQL statements. Without sanitization, this permits arbitrary SQL execution during authentication flows.

Buffer Overflow: Off-by-one errors during string copying and buffer operations allow remote unauthenticated attackers to cause out-of-bounds writes or denial-of-service.

Buffer Overflow: Fragmented payload decoding loops can bypass size-limit checks if the validation is misplaced, leading to heap buffer overflows during packet processing.
