Title: DSA-2243-1 unbound -- design flaw
Description: It was discovered that Unbound, a caching DNS resolver, ceases to provide answers for zones signed using DNSSEC after it has processed a crafted query. 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.
