CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:M/Au:N/C:N/I:C/A:C

Technical Details:
Multiple security issues have been discovered in puppet, a centralized configuration management system. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2011-3848 Kristian Erik Hermansen reported that an unauthenticated directory traversal could drop any valid X.509 Certificate Signing Request at any location on disk, with the privileges of the Puppet Master application. CVE-2011-3870 Ricky Zhou discovered a potential local privilege escalation in the ssh_authorized_keys resource and theoretically in the Solaris and AIX providers, where file ownership was given away before it was written, leading to a possibility for a user to overwrite arbitrary files as root, if their authorized_keys file was managed. CVE-2011-3869 A predictable file name in the k5login type leads to the possibility of symlink attacks which would allow the owner of the home directory to symlink to anything on the system, and have it replaced with the correct content of the file, which can lead to a privilege escalation on puppet runs. CVE-2011-3871 A potential local privilege escalation was found in the --edit mode of 'puppet resource' due to a persistent, predictable file name, which can result in editing an arbitrary target file, and thus be be tricked into running that arbitrary file as the invoking user. This command is most commonly run as root, this leads to a potential privilege escalation. Additionally, this update hardens the indirector file backed terminus base class against injection attacks based on trusted path names. For the oldstable distribution (lenny), this problem will be fixed soon. For the stable distribution (squeeze), this problem has been fixed in version 2.6.2-5+squeeze1. For the testing distribution (wheezy), this has been fixed in version 2.7.3-3. For the unstable distribution (sid), this problem has been fixed in version 2.7.3-3.

Recommendations:
We recommend that you upgrade your puppet Linux Distribution Packages.

Summary:
The remote host is missing an update to puppet announced via advisory DSA 2314-1.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
