medium Nessus Plugin ID 61652

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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

- 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.

Solution

Upgrade the pcp packages.

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