Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Attackers can supply arbitrarily large frame sizes in packet headers, forcing the application to allocate massive vectors and crash due to out-of-memory errors. The fix implemented a 64MB hard limit to prevent this resource exhaustion.
