puppet - programming error

It was discovered that Puppet, a centralized configuration management
solution, misgenerated certificates if the certdnsnames option was
used. This could lead to man in the middle attacks. More details are
available on the Puppet web site.

For the oldstable distribution (lenny), this problem has been fixed in
version 0.24.5-3+lenny2.

For the stable distribution (squeeze), this problem has been fixed in
version 2.6.2-5+squeeze3.

For the unstable distribution (sid), this problem has been fixed in
version 2.7.6-1.

We recommend that you upgrade your puppet packages.
