Resolve insecure temporary file use flaws in PCP shell scripts

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.

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.

pcp was updated to version 3.6.10 which fixes security issues and also brings a lot of new features.

  - Update to pcp-3.6.10. o Transition daemons to run under     an unprivileged account. o Fixes for security advisory     CVE-2012-5530: tmpfile flaws; (bnc#782967). o Fix pcp(1)     command short-form pmlogger reporting. o Fix pmdalogger     error handling for directory files. o Fix pmstat     handling of odd corner case in CPU metrics. o Correct     the python ctype used for pmAtomValue 32bit ints. o Add     missing RPM spec dependency for python-ctypes. o     Corrections to pmdamysql metrics units. o Add pmdamysql     slave status metrics. o Improve pmcollectl error     messages. o Parameterize pmcollectl CPU counts in     interrupt subsys. o Fix generic RPM packaging for     powerpc builds. o Fix python API use of reentrant libpcp     string routines. o Python code backporting for RHEL5 in     qa and pmcollectl. o Fix edge cases in capturing     interrupt error counts.

  - Update to pcp-3.6.9. o Python wrapper for the pmimport     API o Make sar2pcp work with the sysstat versions from     RHEL5, RHEL6, and all recent Fedora versions (which is     almost all current versions of sysstat verified). o     Added a number of additional metrics into the importer     for people starting to use it to analyse sar data from     real customer incidents. o Rework use of C99 'restrict'     keyword in pmdalogger (Debian bug: 689552) o Alot of     work on the PCP QA suite, special thanks to Tomas     Dohnalek for all his efforts there. o Win32 build     updates o Add 'raw' disk active metrics so that existing     tools like iostat can be emulated o Allow sar2pcp to     accept XML input directly (.xml suffix), allowing it to     not have to run on the same platform as the sadc/sadf     that originally generated it. o Add PMI error codes into     the PCP::LogImport perl module. o Fix a typo in pmiUnits     man page synopsis section o Resolve pmdalinux ordering     issue in NUMA/CPU indom setup (Redhat bug: 858384) o     Remove unused pmcollectl imports (Redhat bug: 863210) o     Allow event traces to be used in libpcp interpolate mode

  - Update to pcp-3.6.6. o Added the python PMAPI bindings     and an initial python client in pmcollectl. Separate,     new package exists for python libs for those platforms     that split out packages (rpm, deb). o Added a     pcp-testsuite package for those platforms that might     want this (rpm, deb again, mainly) o Re-introduced the     pcp/qa subdirectory in pcp and deprecated the external     pcpqa git tree. o Fix potential buffer overflow in     pmlogger host name handling. o Reworked the configure
    --prefix handling to be more like the rest of the open     source world. o Ensure the __pmDecodeText ident     parameter is always set Resolves Red Hat bugzilla bug     #841306.
