CVE:CVE-2012-3421 (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.")
 CVE-2012-3420 (Multiple memory leaks in Performance Co-Pilot (PCP) before 3.6.5 allow remote attackers to cause a denial of service (memory consumption or daemon crash) via a large number of PDUs with (1) a crafted context number to the DoFetch function in pmcd/src/dofetch.c or (2) a negative type value to the __pmGetPDU function in libpcp/src/pdu.c.)
 CVE-2012-3419 (Performance Co-Pilot (PCP) before 3.6.5 exports some of the /proc file system, which allows attackers to obtain sensitive information such as proc/pid/maps and command line arguments.)
 CVE-2012-3418 (libpcp in Performance Co-Pilot (PCP) before 3.6.5 allows remote attackers to cause a denial of service and possibly execute arbitrary code via (1) a PDU with the numcreds field value greater than the number of actual elements to the __pmDecodeCreds function in p_creds.c; (2) the string byte number value to the __pmDecodeNameList function in p_pmns.c; (3) the numids value to the __pmDecodeIDList function in p_pmns.c; (4) unspecified vectors to the __pmDecodeProfile function in p_profile.c; the (5) status number value or (6) string number value to the __pmDecodeNameList function in p_pmns.c; (7) certain input to the __pmDecodeResult function in p_result.c; (8) the name length field (namelen) to the DecodeNameReq function in p_pmns.c; (9) a crafted PDU_FETCH request to the __pmDecodeFetch function in p_fetch.c; (10) the namelen field in the __pmDecodeInstanceReq function in p_instance.c; (11) the buflen field to the __pmDecodeText function in p_text.c; (12) PDU_INSTANCE packets to the __pmDecodeInstance in p_in)
