Ubuntu Security Notice USN-1419-1
April 11, 2012

puppet vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- - Ubuntu 11.10
- - Ubuntu 11.04
- - Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in puppet.

Software Description:
- - puppet: Centralized configuration management

Details:

It was discovered that Puppet used a predictable filename when downloading Mac
OS X package files. A local attacker could exploit this to overwrite arbitrary
files. (CVE-2012-1906)

It was discovered that Puppet incorrectly handled filebucket retrieval
requests. A local attacker could exploit this to read arbitrary files.
(CVE-2012-1986)

It was discovered that Puppet incorrectly handled filebucket store requests. A
local attacker could exploit this to perform a denial of service via resource
exhaustion. (CVE-2012-1987)

It was discovered that Puppet incorrectly handled filebucket requests. A local
attacker could exploit this to execute arbitrary code via a crafted file path.
(CVE-2012-1988)

It was discovered that Puppet used a predictable filename for the Telnet
connection log file. A local attacker could exploit this to overwrite arbitrary
files. This issue only affected Ubuntu 11.10. (CVE-2012-1989)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
  puppet-common                   2.7.1-1ubuntu3.6

Ubuntu 11.04:
  puppet-common                   2.6.4-2ubuntu2.9

Ubuntu 10.04 LTS:
  puppet-common                   0.25.4-2ubuntu6.7

In general, a standard system update will make all the necessary changes.
