Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Buffer Overflow: Multiple overflows in SIP header parsing (Call-ID, Warning, media format) due to unbounded string copies from regex captures; some fixed with strncpy/sscanf width limits but the pattern recurs across sub-parsers.
Buffer Overflow: Stack overflow in user-part attribute extraction and SIP attribute getters; fixed by adding size clamping and bounded sprintf, but similar getter code paths remain potential variants.
Buffer Overflow: HEPv3 AUTH_KEY handling used fixed-size password buffer with memcpy based on attacker-controlled length; one fix added bounds check, another changed to dynamic allocation—both for same sink, indicating incomplete remediation risk.
