BIND 9.7.1 and 9.7.1-P1, when a recursive validating server has a trust anchor that is configured statically or via DNSSEC Lookaside Validation (DLV), allows remote attackers to cause a denial of service (infinite loop) via a query for an RRSIG record whose answer is not in the cache, which causes BIND to repeatedly send RRSIG queries to the authoritative servers.

The remote NewStart CGSL host, running version MAIN 6.02, has bind packages installed that are affected by multiple vulnerabilities:

  - ISC BIND 9 through 9.5.0a5 uses a weak random number generator during generation of DNS query ids when     answering resolver questions or sending NOTIFY messages to slave name servers, which makes it easier for     remote attackers to guess the next query id and perform DNS cache poisoning. (CVE-2007-2926)

  - Red Hat Enterprise Linux 5 and Fedora install the Bind /etc/rndc.key file with world-readable permissions,     which allows local users to perform unauthorized named commands, such as causing a denial of service by     stopping named. (CVE-2007-6283)

  - Off-by-one error in the inet_network function in libbind in ISC BIND 9.4.2 and earlier, as used in libc in     FreeBSD 6.2 through 7.0-PRERELEASE, allows context-dependent attackers to cause a denial of service     (crash) and possibly execute arbitrary code via crafted input that triggers memory corruption.
    (CVE-2008-0122)

  - The DNS protocol, as implemented in (1) BIND 8 and 9 before 9.5.0-P1, 9.4.2-P1, and 9.3.5-P1; (2)     Microsoft DNS in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP1 and SP2; and other implementations     allow remote attackers to spoof DNS traffic via a birthday attack that uses in-bailiwick referrals to     conduct cache poisoning against recursive resolvers, related to insufficient randomness of DNS transaction     IDs and source ports, aka DNS Insufficient Socket Entropy Vulnerability or the Kaminsky bug.
    (CVE-2008-1447)

  - BIND 9.6.0, 9.5.1, 9.5.0, 9.4.3, and earlier does not properly check the return value from the OpenSSL     DSA_verify function, which allows remote attackers to bypass validation of the certificate chain via a     malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077. (CVE-2009-0025)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Alternately, an off-path attacker would have to     correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and     message, and spoof a truncated response to trigger an assertion failure, causing the server to exit.

  - The default access control lists (ACL) in ISC BIND 9.4.0, 9.4.1, and 9.5.0a1 through 9.5.0a5 do not set     the allow-recursion and allow-query-cache ACLs, which allows remote attackers to make recursive queries     and query the cache. (CVE-2007-2925)

(CVE-2013-4854)

  - The query_findclosestnsec3 function in query.c in named in ISC BIND 9.6, 9.7, and 9.8 before 9.8.6-P2 and     9.9 before 9.9.4-P2, and 9.6-ESV before 9.6-ESV-R10-P2, allows remote attackers to cause a denial of     service (INSIST assertion failure and daemon exit) via a crafted DNS query to an authoritative nameserver     that uses the NSEC3 signing feature. (CVE-2014-0591)

  - A race condition which may occur when discarding malformed packets can result in BIND exiting due to a     REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1,     9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND     9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1.
    (CVE-2019-6471)

  - A malicious actor who intentionally exploits this lack of effective limitation on the number of fetches     performed when processing referrals can, through the use of specially crafted referrals, cause a recursing     server to issue a very large number of fetches in an attempt to process the referral. This has at least     two potential effects: The performance of the recursing server can potentially be degraded by the     additional work required to perform these fetches, and The attacker can exploit this behavior to use the     recursing server as a reflector in a reflection attack with a high amplification factor. (CVE-2020-8616)

  - Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an     inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the     server. Since BIND, by default, configures a local session key even on servers whose configuration does     not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating     from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately     exits. Prior to the introduction of the check the server would continue operating in an inconsistent     state, with potentially harmful results. (CVE-2020-8617)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

A DoS vulnerability in bind's DNSSEC code has been fixed which occured while recursively validating a server. CVE-2010-0213 has been assigned to this issue.

RRSIG query handling bug in BIND 9.7.1 (CVE-2010-0213) http://www.isc.org/software/bind/advisories/CVE-2010-0213

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its version number, the remote installation of BIND suffers from a denial of service vulnerability.  The vulnerability exists due to an error when handling requests for the 'RRSIG' record type where the answer is not already in the cache. This can lead to BIND entering an infinite loop generating 'RRSIG' queries to the authoritative server.

The remote host is running BIND, an open source name server.  

Versions of BIND 9.7.1 earlier than 9.7.1 P2 are potentially affected by a remote denial of service vulnerability when handling specially crafted queries for 'RRSIG' records.
