<title>BIND: Incorrect signature verification</title>
|

|

<synopsis>
|

|
|

|

|
|
records authenticated using DNSSEC.

ISC BIND is the Internet Systems Consortium implementation of the
|
||
|
|
Domain Name System (DNS) protocol.

|
<p>
|
||
|
|
BIND does not properly check the return value from the OpenSSL
|
||
|
|
functions to verify DSA (CVE-2009-0025) and RSA (CVE-2009-0265)
|
||
|
|
certificates.

<impact type="normal">
|
||
|
|
<p>
|
||
|
|
A remote attacker could bypass validation of the certificate chain to
|
||
|
|
spoof DNSSEC-authenticated records.

|
||

<workaround>
|

|
|
<p>
|
||
|
|
There is no known workaround at this time.

<resolution>

All BIND users should upgrade to the latest version:
