In addition, this update improves the level of DNSSEC support in the lenny version of Unbound so that it is possible for system administrators to configure the trust anchor for the root zone.

For the oldstable distribution (lenny), this problem has been fixed in version 1.4.6-1~lenny1.

For the other distributions (squeeze, wheezy, sid), this problem has been fixed in version 1.4.4-1.

We recommend that you upgrade your unbound packages.");
