We apologize for the inconvenience.
Original advisory details:
It was discovered that Puppet unsafely opened files when the k5login type
is used to manage files. A local attacker could exploit this to overwrite
arbitrary files which could be used to escalate privileges. (CVE-2011-3869)
Ricky Zhou discovered that Puppet did not drop privileges when creating
SSH authorized_keys files. A local attacker could exploit this to overwrite
arbitrary files as root. (CVE-2011-3870)
It was discovered that Puppet used a predictable filename when using the
--edit resource. A local attacker could exploit this to edit arbitrary
files or run arbitrary code as the user invoking the program, typically
root. (CVE-2011-3871)");
