A would-be attacker who is allowed to change zone content could theoretically introduce such a record in order to exploit this condition to cause denial of service, though we consider the use of this vector unlikely because any such attack would require a significant privilege level and be easily traceable.\n\n * CVE-2020-8622: In BIND 9.0.0 -\u003e 9.11.21, 9.12.0 -\u003e 9.16.5, 9.17.0 -\u003e 9.17.3, also affects 9.9.3-S1 -\u003e 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating the server receiving the TSIG-signed request, could send a truncated response to that request, triggering an assertion failure, causing the server to exit. 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.\n\n * CVE-2020-8623: In BIND 9.10.0 -\u003e 9.11.21, 9.12.0 -\u003e 9.16.5, 9.17.0 -\u003e 9.17.3, also affects 9.10.5-S1 -\u003e 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker that can reach a vulnerable system with a specially crafted query packet can trigger a crash. To be vulnerable, the system must: * be running BIND that was built with \"--enable-native-pkcs11\" * be signing one or more zones with an RSA key * be able to receive queries from a possible attacker\n\n * CVE-2020-8624: In BIND 9.9.12 -\u003e 9.9.13, 9.10.7 -\u003e 9.10.8, 9.11.3 -\u003e 9.11.21, 9.12.1 -\u003e 9.16.5, 9.17.0 -\u003e 9.17.3, also affects 9.9.12-S1 -\u003e 9.9.13-S1, 9.11.3-S1 -\u003e 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker who has been granted privileges to change a specific subset of the zone's content could abuse these unintended additional privileges to update other contents of the zone.", "Advisory": { "From": "errata.altlinux.org", "Severity": "High", "Rights": "Copyright 2024 BaseALT Ltd.", "Issued": { "Date": "2020-08-26" }, "Updated": { "Date": "2020-08-26" }, "BDUs": [ { "ID": "BDU:2021-01693", "CVSS": "AV:N/AC:M/Au:N/C:N/I:N/A:P", "CVSS3": "AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L", "CWE": "CWE-269", "Href": "https://bdu.fstec.ru/vul/2021-01693", "Impact": "Low", "Public": "20200820" }, { "ID": "BDU:2021-01725", "CVSS": "AV:N/AC:L/Au:S/C:N/I:N/A:P", "CVSS3": "AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L", "CWE": "CWE-617", "Href": "https://bdu.fstec.ru/vul/2021-01725", "Impact": "Low", "Public": "20200820" }, { "ID": "BDU:2021-01726", "CVSS": "AV:N/AC:L/Au:S/C:N/I:P/A:N", "CVSS3": "AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N", "CWE": "CWE-269", "Href": "https://bdu.fstec.ru/vul/2021-01726", "Impact": "Low", "Public": "20200820" } ], "CVEs": [ { "ID": "CVE-2020-8619", "CVSS": "AV:N/AC:L/Au:S/C:N/I:N/A:P", "CVSS3": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H", "CWE": "CWE-404", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2020-8619", "Impact": "Low", "Public": "20200617" }, { "ID": "CVE-2020-8622", "CVSS": "AV:N/AC:L/Au:S/C:N/I:N/A:P", "CVSS3": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "CWE": "CWE-617", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2020-8622", "Impact": "Low", "Public": "20200821" }, { "ID": "CVE-2020-8623", "CVSS": "AV:N/AC:M/Au:N/C:N/I:N/A:P", "CVSS3": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "CWE": "CWE-617", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2020-8623", "Impact": "High", "Public": "20200821" }, { "ID": "CVE-2020-8624", "CVSS": "AV:N/AC:L/Au:S/C:N/I:P/A:N", "CVSS3": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N", "CWE": "CWE-269", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2020-8624", "Impact": "Low", "Public": "20200821" } ], "AffectedCPEs": { "CPEs": [ "cpe:/o:alt:kworkstation:9", "cpe:/o:alt:workstation:9", "cpe:/o:alt:server:9", "cpe:/o:alt:server-v:9", "cpe:/o:alt:education:9", "cpe:/o:alt:slinux:9", "cpe:/o:alt:starterkit:p9" ] } } }, "Criteria": { "Operator": "AND", "Criterions": [ { "TestRef": "oval:org.altlinux.errata:tst:1001", "Comment": "ALT Linux must be installed" } ], "Criterias": [ { "Operator": "OR", "Criterions": [ { "TestRef": "oval:org.altlinux.errata:tst:20202685001", "Comment": "bind is earlier than 0:9.11.22-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20202685002", "Comment": "bind-devel is earlier than 0:9.11.22-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20202685003", "Comment": "bind-doc is earlier than 0:9.11.22-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20202685004", "Comment": "bind-utils is earlier than 0:9.11.22-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20202685005", "Comment": "libbind is earlier than 0:9.11.22-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20202685006", "Comment": "lwresd is earlier than 0:9.11.22-alt1" } ] } ] } } ] }
