Description Tomas Hoger 2012-06-04 08:19:14 UTC 
ISC has sent a brief notification about a flaw affecting bind 9 versions to be disclosed on Jun 4.  CVE-2012-1667 was assigned to this issue, but there are no other details currently available about this flaw.
Comment 4 Tomas Hoger 2012-06-04 13:25:42 UTC 
Public now via upstream advisory.  The flaw is in the handling of the zero length rdata records, which may trigger named crash, memory disclosure, or zone data corruption in certain configurations.  This primarily affects recursive resolvers.

Issue was fixed in upstream versions:
9.6-ESV-R7-P1, 9.7.6-P1, 9.8.3-P1, and 9.9.1-P1
