Debian: Security update for Performance Co-Pilot

It was discovered that Performance Co-Pilot (pcp), a framework for performance monitoring, contains several vulnerabilites. 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. The “linux” PMDA used by the pmcd daemon discloses sensitive information from the /proc file system to unauthenticated clients. Multiple memory leaks processing crafted requests can cause pmcd to consume large amounts of memory and eventually crash.

Incorrect event-driven programming allows malicious clients to prevent other clients from accessing the pmcd daemon. Updated packages are available from security.debian.org.

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.
