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

<description>
|
|
<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.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could bypass validation of the certificate chain to
|
|
spoof DNSSEC-authenticated records.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All BIND users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-dns/bind-9.4.3_p1"</code>
