Created pdns-recursor tracking bugs for this issue Affects: fedora-all [bug 794965] Affects: epel-all [bug 794966] There's still no patch available. I'm going to build updated packages as soon as a patch is available. From http://doc.powerdns.com/changelog.html#changelog-recursor-3.5: "While Recursor 3.3 was not vulnerable to the specific attack noted in 'Ghost Domain Names: Revoked Yet Still Resolvable', further investigation showed that a variant of the attack could work. This was fixed in r3085." http://wiki.powerdns.com/trac/changeset/3085 related: http://wiki.powerdns.com/trac/changeset/3084 http://wiki.powerdns.com/trac/changeset/3083 http://wiki.powerdns.com/trac/changeset/3082 There's also the following upstream bug: http://wiki.powerdns.com/trac/ticket/668 pdns-recursor-3.5-1.fc19 has been pushed to the Fedora 19 stable repository.

This was fixed in commit 3085. This should also close the slightly bogus CVE-2012-1193. Closes ticket 668." |
