Recurring patterns

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

Denial of Service: Process crash (denial of service) triggered when temporary file creation is attempted within thread-local destructors, caused by accessing deallocated thread-local RNG storage during name generation. This is fixed by utilizing a fallback RNG mechanism.

Denial of Service: Memory exhaustion and bypass of disk-rollover thresholds due to integer overflows and truncation during size limit checks in SpooledTempFile, allowing excessive memory allocation.
