CVE-2012-3418
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedlibpcp 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencelibpcp in Performance Co-Pilot (PCP) before 3.6.5 contains multiple memory corruption vulnerabilities across 14 different PDU decoding functions (__pmDecodeCreds, __pmDecodeNameList, __pmDecodeIDList, __pmDecodeProfile, __pmDecodeResult, DecodeNameReq, __pmDecodeFetch, __pmDecodeInstanceReq, __pmDecodeText, __pmDecodeInstance, __pmDecodeLogControl). Malformed PDU inputs with oversized field values (numcreds, numids, namelen, buflen, etc.) trigger integer overflows, heap-based buffer overflows, and buffer over-reads, potentially allowing remote denial of service or arbitrary code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if PCP is installedRun 'rpm -qa | grep -i pcp' for Red Hat-based systems, 'dpkg -l | grep -i pcp' for Debian-based, or check for /usr/lib/libpcp* or /usr/local/lib/libpcp* filesAffected if No PCP packages or libpcp library files found means not affected
-
Determine installed PCP versionRun 'pcp --version' or 'pmversion' command, or query the package manager: 'rpm -q pcp' or 'dpkg -s pcp'Affected if Version is 3.6.4 or earlier, or is one of 2.1.1 through 2.1.11 - compare against affected ranges
-
Check if PCP services are runningRun 'ps aux | grep -E "pmcd|pmlogger"' or check for listening ports using 'netstat -anp | grep -E ":5432|:5230|:5231|:5232"'Affected if PCP daemon (pmcd) or related services are running and network-accessible increases exposure to remote exploitation
-
Verify vulnerable PDU decoding libraryCheck libpcp version directly: 'ls -la /usr/lib/libpcp*' or 'strings /usr/lib/libpcp.so* | grep "libpcp" | head -5'Affected if The libpcp library exists and version cannot be determined as 3.6.5 or later indicates potential vulnerability
System is affected if PCP/libpcp is installed with version 3.6.4 or earlier, or any version 2.1.1-2.1.11, and the PCP services are exposed to network or untrusted inputs.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to PCP version 3.6.5 or later. If upgrading is not immediately feasible, restrict network access to PCP services and implement input validation at network boundaries.
