CVE-2012-3421 is a vulnerability of currently unknown severity. 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.". EPSS estimates a 3.33% chance of exploitation in the next 30 days.
