Detail

Synopsis

Incomplete verification of RSA and DSA certificates might lead to spoofed records authenticated using DNSSEC.

Background

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

Description

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

A remote attacker could bypass validation of the certificate chain to spoof DNSSEC-authenticated records.

Workaround

There is no known workaround at this time.

Resolution

All BIND users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/bind-9.4.3_p1"

Title: DSA-1703-1 bind9 -- interpretation conflict
Description: It was discovered that BIND, an implementation of the DNS protocol suite, does not properly check the result of an OpenSSL function which is used to verify DSA cryptographic signatures. As a result, incorrect DNS resource records in zones protected by DNSSEC could be accepted as genuine. For the stable distribution, this problem has been fixed in version 1:9.3.4-2etch4. For the unstable distribution and the testing distribution, this problem will be fixed soon. We recommend that you upgrade your BIND packages.

Description: It was discovered that Bind did not properly perform certificate verification. When DNSSEC with DSA certificates are in use, a remote attacker could exploit this to bypass certificate validation to spoof DNS entries and poison DNS caches. Among other things, this could lead to misdirected email and web traffic.

Title: RHSA-2009:0020 -- bind security update (Moderate)
Description: Updated Bind packages to correct a security issue are now available for Red Hat Enterprise Linux 2.1, 3, 4, and 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. A flaw was discovered in the way BIND checked the return value of the OpenSSL DSA_do_verify function. On systems using DNSSEC, a malicious zone could present a malformed DSA certificate and bypass proper certificate validation, allowing spoofing attacks. (CVE-2009-0025)
