announced by ISC dated 31 October (delivered via e-mail to the
bind-announce@isc.org list on 2 November):
Description:
Because of OpenSSL's recently announced vulnerabilities
(CAN-2006-4339, CVE-2006-2937 and CVE-2006-2940) which affect named,
we are announcing this workaround and releasing patches. A proof of
concept attack on OpenSSL has been demonstrated for CAN-2006-4339.
OpenSSL is required to use DNSSEC with BIND.
Fix for version 9.3.2-P1 and lower:
Upgrade to BIND 9.3.2-P2, then generate new RSASHA1 and
RSAMD5 keys for all old keys using the old default exponent
and perform a key rollover to these new keys.
These versions also change the default RSA exponent to be
65537 which is not vulnerable to the attacks described in
CAN-2006-4339.
