Description Josh Bressers 2009-04-07 12:28:06 UTC
BIND before 9.2.6-P1 and 9.3.x before 9.3.2-P1 allows remote attackers to
cause a denial of service (crash) via a flood of recursive queries, which
cause an INSIST failure when the response is received after the recursion
queue is empty.

Comment 3 Josh Bressers 2009-04-07 16:51:10 UTC
This is fixed in Red Hat Enterprise Linux 3 and 4 by the patch

It was fixed in the errata RHBA-2006:0287 and RHBA-2006:0288.

They are not marked as RHSA errata as the patch went in before it was recognized as being a security relevant fix. The errata do however note the CVE id in question.
