Recurring patterns

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

Buffer Overflow: Integer overflows in protocol parsing logic (such as key or body length checks) allow attackers to cause heap overflows during binary and SASL processing. Safe bounding and explicit limit validation are required.
Auth Bypass: Implicit dependence on SASL state engines rather than explicit state boolean trackers on connection structures has historically permitted authentication bypasses.
Use After Free: Complexity in managing connection and request buffer lifecycles inside the proxy pipeline often leads to early reclamation of backend buffers, causing crashes or memory corruption.
