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_instance.c; or the (13) c_numpmid or (14) v_numval fields to the __pmDecodeLogControl function in p_lcontrol.c, which triggers integer overflows, heap-based buffer overflows, and/or buffer over-reads.
