SunOS 5.8_x86: libresolv.so.2, in.named an.
Date this patch was last updated by Sun : Mar/09/09

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has dnsmasq packages installed that are affected by multiple vulnerabilities:

  - 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)

  - Heap-based buffer overflow in the tftp_request function in tftp.c in dnsmasq before 2.50, when --enable-     tftp is used, might allow remote attackers to execute arbitrary code via a long filename in a TFTP packet,     as demonstrated by a read (aka RRQ) request. (CVE-2009-2957)

  - The tftp_request function in tftp.c in dnsmasq before 2.50, when --enable-tftp is used, allows remote     attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a TFTP read (aka     RRQ) request with a malformed blksize option. (CVE-2009-2958)

  - Dnsmasq before 2.66test2, when used with certain libvirt configurations, replies to queries from     prohibited interfaces, which allows remote attackers to cause a denial of service (traffic amplification)     via spoofed TCP based DNS queries. NOTE: this vulnerability exists because of an incomplete fix for     CVE-2012-3411. (CVE-2013-0198)

  - A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq     checks in the forward.c:reply_query() if the reply destination address/port is used by the pending     forwarded queries. However, it does not use the address/port to retrieve the exact forwarded query,     substantially reducing the number of attempts an attacker on the network would have to perform to forge a     reply and get it accepted by dnsmasq. This issue contrasts with RFC5452, which specifies a query's     attributes that all must be used to match a reply. This flaw allows an attacker to perform a DNS Cache     Poisoning attack. If chained with CVE-2020-25685 or CVE-2020-25686, the attack complexity of a successful     attack is reduced. The highest threat from this vulnerability is to data integrity. (CVE-2020-25684)

  - A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq     checks in forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a     weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC, SHA-1     when it is) this flaw allows an off-path attacker to find several different domains all having the same     hash, substantially reducing the number of attempts they would have to perform to forge a reply and get it     accepted by dnsmasq. This is in contrast with RFC5452, which specifies that the query name is one of the     attributes of a query that must be used to match a reply. This flaw could be abused to perform a DNS Cache     Poisoning attack. If chained with CVE-2020-25684 the attack complexity of a successful attack is reduced.
    The highest threat from this vulnerability is to data integrity. (CVE-2020-25685)

  - A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an     existing pending request for the same name and forwards a new request. By default, a maximum of 150     pending queries can be sent to upstream servers, so there can be at most 150 queries for the same name.
    This flaw allows an off-path attacker on the network to substantially reduce the number of attempts that     it would have to perform to forge a reply and have it accepted by dnsmasq. This issue is mentioned in the     Birthday Attacks section of RFC5452. If chained with CVE-2020-25684, the attack complexity of a     successful attack is reduced. The highest threat from this vulnerability is to data integrity.
    (CVE-2020-25686)

  - An issue was discovered in Dnsmasq before 2.90. The default maximum EDNS.0 UDP packet size was set to 4096     but should be 1232 because of DNS Flag Day 2020. (CVE-2023-28450)

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

s700_800 11.23 Bind 9.2.0 components : 

A potential vulnerability has been identified with HP-UX running BIND.
The vulnerability could be exploited remotely to cause DNS cache poisoning.

Updated bind packages that help mitigate DNS spoofing attacks are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

[Updated 10th July 2008] We have updated the Enterprise Linux 5 packages in this advisory. The default and sample caching-nameserver configuration files have been updated so that they do not specify a fixed query-source port. Administrators wishing to take advantage of randomized UDP source ports should check their configuration file to ensure they have not specified fixed query-source ports.

ISC BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols.

The DNS protocol protects against spoofing attacks by requiring an attacker to predict both the DNS transaction ID and UDP source port of a request. In recent years, a number of papers have found problems with DNS implementations which make it easier for an attacker to perform DNS cache-poisoning attacks.

Previous versions of BIND did not use randomized UDP source ports. If an attacker was able to predict the random DNS transaction ID, this could make DNS cache-poisoning attacks easier. In order to provide more resilience, BIND has been updated to use a range of random UDP source ports. (CVE-2008-1447)

Note: This errata also updates SELinux policy on Red Hat Enterprise Linux 4 and 5 to allow BIND to use random UDP source ports.

Users of BIND are advised to upgrade to these updated packages, which contain a backported patch to add this functionality.

Red Hat would like to thank Dan Kaminsky for reporting this issue.

9.5.0-P1 release which contains fix for CVE-2008-1447. This update also fixes typo in bind-sdb summary and fixes parsing of inner ACLs.

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.

The transaction id and the udp source port used for DNS queries by the bind nameserver were predicatable. Attackers could potentially exploit that weakness to manipulate the DNS cache ('DNS cache poisoning', CVE-2008-1447).

The transaction id and the UDP source port used for DNS queries by the bind nameserver were predicatable. Attackers could potentially exploit that weakness to manipulate the DNS cache ('DNS cache poisoning', CVE-2008-1447).

The remote host is affected by the vulnerability described in GLSA-200809-02 (dnsmasq: Denial of Service and DNS spoofing)

    Dan Kaminsky of IOActive reported that dnsmasq does not randomize UDP     source ports when forwarding DNS queries to a recursing DNS server     (CVE-2008-1447).
    Carlos Carvalho reported that dnsmasq in the 2.43 version does not     properly handle clients sending inform or renewal queries for unknown     DHCP leases, leading to a crash (CVE-2008-3350).
  Impact :

    A remote attacker could send spoofed DNS response traffic to dnsmasq,     possibly involving generating queries via multiple vectors, and spoof     DNS replies, which could e.g. lead to the redirection of web or mail     traffic to malicious sites. Furthermore, an attacker could generate     invalid DHCP traffic and cause a Denial of Service.
  Workaround :

    There is no known workaround at this time.

New ruby packages are available for Slackware 11.0, 12.0, and 12.1 to fix bugs and a security issue.

The transaction id and the udp source port used for DNS queries by the bind nameserver were predictable. Attackers could potentially exploit that weakness to manipulate the DNS cache ('DNS cache poisoning', CVE-2008-1447).

Additionally the root.hint zone file was updated to contain the new IP number of the 'L' root DNS server.

The remote Oracle Linux 5 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2008-0789 advisory.

    - fixes for CVE-2008-1447/CERT VU#800113

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

According to its self-reported version number, the Microsoft DNS Server running on the remote host contains issues in the DNS library that could allow an attacker to send malicious DNS responses to DNS requests made by the remote host thereby spoofing or redirecting internet traffic from legitimate locations.
