The pduread function in pdu.c in libpcp in Performance Co-Pilot (PCP) before 3.6.5 does not properly time out connections, which allows remote attackers to cause a denial of service (pmcd hang) by sending individual bytes of a PDU separately, related to an "event-driven programming flaw."

Security readout for executives and security teams

This issue can let a remote attacker make Performance Co-Pilot's monitoring daemon hang by holding a connection open too slowly. The business impact is availability loss for systems relying on PCP telemetry, not data theft or code execution based on the supplied sources. Exposure is most relevant where PCP or libpcp versions before 3.6.5 are installed and pmcd is reachable over a network. The source bundle does not identify specific distributions beyond advisory references. Treat as a targeted availability risk for monitoring infrastructure. Prioritize exposed or production PCP deployments, especially where monitoring loss could delay incident response or operational recovery. Mitigation focus: Inventory systems running Performance Co-Pilot or libpcp.; Upgrade PCP/libpcp to 3.6.5 or vendor-fixed packages.; Apply relevant Debian, Fedora, openSUSE, or SUSE advisories where applicable..
