Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Unbounded socket allocation and socket leaks can occur when socket counts are bypassed during ECONNRESET timeouts or option mutation, leading to rapid resource exhaustion. Developers must enforce strict socket count ceilings and clone option objects to prevent configuration bleed.
Denial of Service: Reused or idle keepalive sockets can hang indefinitely and consume file descriptors if socket timeouts are manually computed or misconfigured. Utilizing native socket deadlines is critical to prevent hung connection exhaustion.
Auth Bypass: Parsing errors during IPv6 extraction from HTTP Host headers can lead to incorrect TLS SNI routing, effectively skipping host verification checks. Strict canonicalization and prefix verification of the parsed hostname must be enforced.
