CPU Exhaustion

Neethi is vulnerable to CPU Exhaustion. The vulnerability is due to an exponential‑time algorithm in Neethi's policy‑intersection logic, where a specially crafted pair of WS‑Policy documents trigger the policy-intersection routine to perform exponential work, pinning the CPU for an extended perio...
