VAR-202101-0220
Vulnerability from variot - Updated: 2026-03-09 21:24A 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. Dnsmasq is a lightweight DNS forwarding and DHCP and TFTP server written in C language.
For the stable distribution (buster), these problems have been fixed in version 2.80-1+deb10u1.
For the detailed security status of dnsmasq please refer to its security tracker page at: https://security-tracker.debian.org/tracker/dnsmasq

Synopsis: Important: Red Hat Virtualization Host security bug fix and enhancement update [ovirt-4.4.4] Advisory ID: RHSA-2021:0401-01 Product: Red Hat Virtualization Advisory URL: https://access.redhat.com/errata/RHSA-2021:0401 Issue date: 2021-02-03 CVE Names: CVE-2020-25684 CVE-2020-25685 CVE-2020-25686 CVE-2021-3156 ==================================================================== 1. Summary:
An update for imgbased, redhat-release-virtualization-host, and redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
- Relevant releases/architectures:
RHEL 8-based RHEV-H for RHEV 4 (build requirements) - noarch, x86_64 Red Hat Virtualization 4 Hypervisor for RHEL 8 - noarch, x86_64 Red Hat Virtualization 4 Management Agent for RHEL 7 Hosts - noarch
- Description:
The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.
Security Fix(es):
-
sudo: Heap buffer overflow in argument parsing (CVE-2021-3156)
-
dnsmasq: loose address/port check in reply_query() makes forging replies easier for an off-path attacker (CVE-2020-25684)
-
dnsmasq: loose query name check in reply_query() makes forging replies easier for an off-path attacker (CVE-2020-25685)
-
dnsmasq: multiple queries forwarded for the same name makes forging replies easier for an off-path attacker (CVE-2020-25686)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
- Previously, the Red Hat Virtualization Host (RHV-H) repository (rhvh-4-for-rhel-8-x86_64-rpms) did not include the libsmbclient package, which is a dependency for the sssd-ad package. Consequently, the sssd-ad package failed to install.
With this update, the libsmbclient is now in the RHV-H repository, and sssd-ad now installs on RHV-H. (BZ#1868967)
- Solution:
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/2974891
After installing this update, the smb service will be restarted automatically.

"data": "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\u0027s 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. Dnsmasq is a lightweight DNS forwarding and DHCP and TFTP server written in C language. \n\nFor the stable distribution (buster), these problems have been fixed in\nversion 2.80-1+deb10u1. \n\nFor the detailed security status of dnsmasq please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/dnsmasq\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n\niQEzBAEBCgAdFiEEAqSkbVtrXP4xJMh3EL6Jg/PVnWQFAmAZVA4ACgkQEL6Jg/PV\nnWQYKAgAgVwonRAgXSliaFh0n44OPOz9wf4KibG7otcnAx4V4XqFAeXsHd/hIX/K\nIC313F3I+8WzvjKBhvt2KnGG9SnoTnq4roBIa1nz//vNX0hyfDm5xPlxQOExzC+c\nYS8kGt++SvC2wgOsrZEjyk0ecKqDJmZSwW31zXG9/2kTzCbKjuDp+i4TTADqabPC\nAgbmEGVKBR2Fk7K9Prct27oWoj7LHMaH+Ttb8uQGnG7OgJs9KyRI+2qIu+VaRCGf\nyfRj+XayPYHV1Amf5dLIKcLMMp/FnkNFoO2YIAZkWVPjXD2uPKUykJJ1GRl8R+0q\nqtNhPTNNuD6WnYzC8yP0KIQ2tsbg9Q==\n=j5Ka\n-----END PGP SIGNATURE-----\n. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA256\n\n==================================================================== \nRed Hat Security Advisory\n\nSynopsis: Important: Red Hat Virtualization Host security bug fix and enhancement update [ovirt-4.4.4]\nAdvisory ID: RHSA-2021:0401-01\nProduct: Red Hat Virtualization\nAdvisory URL: https://access.redhat.com/errata/RHSA-2021:0401\nIssue date: 2021-02-03\nCVE Names: CVE-2020-25684 CVE-2020-25685 CVE-2020-25686\n CVE-2021-3156\n====================================================================\n1. Summary:\n\nAn update for imgbased, redhat-release-virtualization-host, and\nredhat-virtualization-host is now available for Red Hat Virtualization 4\nfor Red Hat Enterprise Linux 8. \n\nRed Hat Product Security has rated this update as having a security impact\nof Important. A Common Vulnerability Scoring System (CVSS) base score,\nwhich gives a detailed severity rating, is available for each vulnerability\nfrom the CVE link(s) in the References section. \n\n2. Relevant releases/architectures:\n\nRHEL 8-based RHEV-H for RHEV 4 (build requirements) - noarch, x86_64\nRed Hat Virtualization 4 Hypervisor for RHEL 8 - noarch, x86_64\nRed Hat Virtualization 4 Management Agent for RHEL 7 Hosts - noarch\n\n3. Description:\n\nThe redhat-virtualization-host packages provide the Red Hat Virtualization\nHost. These packages include redhat-release-virtualization-host,\novirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are\ninstalled using a special build of Red Hat Enterprise Linux with only the\npackages required to host virtual machines. RHVH features a Cockpit user\ninterface for monitoring the host\u0027s resources and performing administrative\ntasks. \n\nSecurity Fix(es):\n\n* sudo: Heap buffer overflow in argument parsing (CVE-2021-3156)\n\n* dnsmasq: loose address/port check in reply_query() makes forging replies\neasier for an off-path attacker (CVE-2020-25684)\n\n* dnsmasq: loose query name check in reply_query() makes forging replies\neasier for an off-path attacker (CVE-2020-25685)\n\n* dnsmasq: multiple queries forwarded for the same name makes forging\nreplies easier for an off-path attacker (CVE-2020-25686)\n\nFor more details about the security issue(s), including the impact, a CVSS\nscore, acknowledgments, and other related information, refer to the CVE\npage(s) listed in the References section. \n\nBug Fix(es):\n\n* Previously, the Red Hat Virtualization Host (RHV-H) repository\n(rhvh-4-for-rhel-8-x86_64-rpms) did not include the libsmbclient package,\nwhich is a dependency for the sssd-ad package. Consequently, the sssd-ad\npackage failed to install. \n\nWith this update, the libsmbclient is now in the RHV-H repository, and\nsssd-ad now installs on RHV-H. (BZ#1868967)\n\n4. Solution:\n\nFor details on how to apply this update, which includes the changes\ndescribed in this advisory, refer to:\n\nhttps://access.redhat.com/articles/2974891\n\nAfter installing this update, the smb service will be restarted\nautomatically. \n\n5.
