1 high-severity fix in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: A raw memory management flaw during callback execution can trigger a segmentation fault or use-after-free, allowing remote attackers to reliably crash the loop process. Proper manual reference counting of callables is required when running in user contexts.
Denial of Service: Resource exhaustion can occur due to cumulative memory leaks when SSL connections fail to break circular references during close or connection shutdown sequences.
Denial of Service: Failure to successfully cancel scheduled timeout handles (such as handshake or shutdown timers) due to flawed dynamic lookups on cdef classes keeps entire SSL objects and their associated buffers pinned in memory indefinitely.
