A flaw was found in the PCP (Performance Co-Pilot) pmproxy service. A remote attacker can exploit a vulnerability in the pmLogLoadInDom() function by sending a specially crafted request. This bypasses a critical bounds check, which can lead to the pmproxy service crashing, causing a Denial of Service (DoS). Additionally, this flaw may enable the leakage of sensitive information from the system's memory.
