The remote host is missing an update to puppet announced via advisory DSA 2419-1.

Two vulnerabilities were discovered in Puppet, a centralized configuration management tool. CVE-2012-1053 Puppet runs execs with an unintended group privileges, potentially leading to privilege escalation. CVE-2012-1054 The k5login type writes to untrusted locations, enabling local users to escalate their privileges if the k5login type is used. For the stable distribution (squeeze), these problems have been fixed in version 2.6.2-5+squeeze4. For the testing distribution (wheezy) and the unstable distribution (sid), these problems have been fixed in version 2.7.11-1. We recommend that you upgrade your puppet packages.
