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."

The remote NewStart CGSL host, running version MAIN 6.01, has pcp packages installed that are affected by multiple vulnerabilities:

  - 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.
    (CVE-2012-3418)

  - 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-2012-3419)

  - 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-2012-3420)

  - 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-2012-3421)

  - The (1) pcmd and (2) pmlogger init scripts in     Performance Co-Pilot (PCP) before 3.6.10 allow local     users to overwrite arbitrary files via a symlink attack     on a /var/tmp/##### temporary file. (CVE-2012-5530)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Security and bugfix update. Security flaws fixed include CVE-2012-3418 CVE-2012-3419 CVE-2012-3420 and CVE-2012-3421

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that Performance Co-Pilot (pcp), a framework for performance monitoring, contains several vulnerabilities.

  - CVE-2012-3418     Multiple buffer overflows in the PCP protocol decoders     can cause PCP clients and servers to crash or,     potentially, execute arbitrary code while processing     crafted PDUs.

  - CVE-2012-3419     The 'linux' PMDA used by the pmcd daemon discloses     sensitive information from the /proc file system to     unauthenticated clients.

  - CVE-2012-3420     Multiple memory leaks processing crafted requests can     cause pmcd to consume large amounts of memory and     eventually crash.

  - CVE-2012-3421     Incorrect event-driven programming allows malicious     clients to prevent other clients from accessing the pmcd     daemon.

To address the information disclosure vulnerability, CVE-2012-3419, a new 'proc' PMDA was introduced, which is disabled by default. If you need access to this information, you need to enable the 'proc' PMDA.
