Recurring patterns

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

Denial of Service: Integer overflows during container size calculations can bypass maximum message size checks, allowing malicious payloads to trigger excessive memory allocation or crashes. This vulnerability pattern is widespread across multiple language protocol implementations, including C++ and C-GLib.
Denial of Service: Deeply nested structures can lead to uncontrolled stack recursion during serialization and deserialization, causing stack exhaustion and crashing the daemon. Robust recursion depth limits must be consistently enforced during read/write cycles.
Improper Certificate Validation: Inadequate wildcard certificate validation and lack of peer hostname verification during TLS handshakes can permit Man-in-the-Middle (MitM) attacks. Standard compliance requires rejecting wildcards in non-leftmost labels and enforcing strict verification before finalizing handshakes.
