3 high-severity fixes 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: Unhandled parser exceptions during syntax analysis can cause complete server crashes. This was addressed by introducing guarded execution contexts using protected calls to isolate failures.
Denial of Service: An out-of-bounds memory write during WebSocket mask processing allowed memory corruption and Denial of Service. This required transitioning from a rounded 32-bit word XOR loop to precise byte-by-byte masking.
Memory Safety: Buffer overflows and memory corruption issues occurred in aggregation execution due to allocating vector keys with incorrect sizes, necessitating dedicated vectors with strict size bounds.
