Problem type : remote
Debian-specific: no
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.
