puppet - several

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.
