Debian: Security update for Puppet

Several vulnerabilities have been discovered in puppet, a centralized configuration management system. Puppet is using predictable temporary file names when downloading Mac OS X package files. This allows a local attacker to either overwrite arbitrary files on the system or to install an arbitrary package. When handling requests for a file from a remote filebucket, puppet can be tricked into overwriting its defined location for filebucket storage. This allows an authorized attacker with access to the puppet master to read arbitrary files.

Puppet is incorrectly handling filebucket store requests. This allows an attacker to perform denial of service attacks against puppet by resource exhaustion. Puppet is incorrectly handling filebucket requests. This allows an attacker with access to the certificate on the agent and an unprivileged account on puppet master to execute arbitrary code via crafted file path names and making a filebucket request.

Updated packages are available from security.debian.org.

Several vulnerabilities have been discovered in puppet, a centralized
configuration management system.  The Common Vulnerabilities and
Exposures project identifies the following problems:

CVE-2012-1906

   Puppet is using predictable temporary file names when downloading
   Mac OS X package files.  This allows a local attacker to either
   overwrite arbitrary files on the system or to install an arbitrary
   package.

CVE-2012-1986

   When handling requests for a file from a remote filebucket, puppet
   can be tricked into overwriting its defined location for filebucket
   storage.  This allows an authorized attacker with access to the puppet
   master to read arbitrary files.

CVE-2012-1987

   Puppet is incorrectly handling filebucket store requests.  This allows
   an attacker to perform denial of service attacks against puppet by
   resource exhaustion.

CVE-2012-1988

   Puppet is incorrectly handling filebucket requests.  This allows an
   attacker with access to the certificate on the agent and an unprivileged
   account on puppet master to execute arbitrary code via crafted file
   path names and making a filebucket request.


For the stable distribution (squeeze), this problem has been fixed in
version 2.6.2-5+squeeze5.

For the testing distribution (wheezy), this problem has been fixed in
version 2.7.13-1.

For the unstable distribution (sid), this problem has been fixed in
version 2.7.13-1.

We recommend that you upgrade your puppet packages.
