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. • https://bugzilla.redhat.com/show_bug.cgi?id=1889686 https://lists.debian.org/debian-lts-announce/2021/03/msg00027.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QGB7HL3OWHTLEPSMLDGOMXQKG3KM2QME https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WYW3IR6APUSKOYKL5FT3ACTIHWHGQY32 https://security.gentoo.org/glsa/202101-17 https://www.arista.com/en/support/advisories-notices/security-advisories/12135-security-advisory-61 https://www • CWE-358: Improperly Implemented Security Check for Standard •

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. • https://bugzilla.redhat.com/show_bug.cgi?id=1889688 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QGB7HL3OWHTLEPSMLDGOMXQKG3KM2QME https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WYW3IR6APUSKOYKL5FT3ACTIHWHGQY32 https://security.gentoo.org/glsa/202101-17 https://www.arista.com/en/support/advisories-notices/security-advisories/12135-security-advisory-61 https://www.debian.org/security/2021/dsa-4844 https://www.jsof-tech.com/discl • CWE-326: Inadequate Encryption Strength •

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. • https://bugzilla.redhat.com/show_bug.cgi?id=1890125 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QGB7HL3OWHTLEPSMLDGOMXQKG3KM2QME https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WYW3IR6APUSKOYKL5FT3ACTIHWHGQY32 https://security.gentoo.org/glsa/202101-17 https://www.arista.com/en/support/advisories-notices/security-advisories/12135-security-advisory-61 https://www.debian.org/security/2021/dsa-4844 https://www.jsof-tech.com/discl • CWE-290: Authentication Bypass by Spoofing CWE-358: Improperly Implemented Security Check for Standard •
