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

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