CVE ID         : CVE-2012-3418 CVE-2012-3419 CVE-2012-3420 CVE-2012-3421

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

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.

For the stable distribution (squeeze), this problem has been fixed in
version 3.3.3-squeeze2.

For the unstable distribution (sid), this problem has been fixed in
version 3.6.5.

We recommend that you upgrade your pcp packages.
