CVE-2012-3420: Multiple memory leaks in Performance Co-Pilot (PCP) before 3.6.5 allow remote attackers to cause a denial o...

Security readout for executives and security teams

Performance Co-Pilot before 3.6.5 has memory leak flaws that a remote attacker could use to exhaust memory or crash a daemon. The business impact is availability loss for systems relying on PCP monitoring, not data theft based on the provided sources. Exposure is most relevant where PCP or pmcd from before version 3.6.5 is installed and reachable by untrusted networks. The source bundle does not provide normalized affected package ranges beyond PCP before 3.6.5. Treat this as a targeted availability risk for monitored Linux or UNIX infrastructure. Prioritize internet- or broadly reachable PCP services and critical monitoring hosts, but it is not supported as a confirmed active-exploitation emergency by the provided sources. Mitigation focus: Upgrade PCP to version 3.6.5 or vendor-patched packages.; Apply relevant Fedora, Debian, SUSE, or openSUSE advisories for managed systems.; Restrict PCP service exposure to trusted management networks..
