Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Slow-loris style TLS handshakes can trivially lock server threads, and unconstrained request streams can exhaust system resources. Mandatory data limits and half-close connection management are necessary to mitigate these vectors.
Memory Safety: Unsafe raw pointer cloning in LocalRequest led to aliased mutable references and data races, allowing concurrent threads to violate Rust's memory safety guarantees.
Path Traversal: Inadequate percent-decoded segment validation and unsafe path joining can let attackers traverse out of the intended root directory via FromSegments implementations.
