TITLE

BIND  Cache Pollution with Incorrect Records Vulnerability in

DESCRIPTION

BIND 9.11.0 -> 9.11.36 9.12.0 -> 9.16.26 9.17.0 -> 9.18.0 BIND Supported Preview Editions: 9.11.4-S1 -> 9.11.36-S1 9.16.8-S1 -> 9.16.26-S1 Versions of BIND 9 earlier than those shown - back to 9.1.0, including Supported Preview Editions - are also believed to be affected but have not been tested as they are EOL. The cache could become poisoned with incorrect records leading to queries being made to the wrong servers, which might also result in false information being returned to clients. Bogus NS records supplied by the forwarders may be cached and used by name if it needs to recurse for any reason. This issue causes it to obtain and pass on potentially incorrect answers. (CVE-2021-25220) By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service. (CVE-2022-2795) By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. (CVE-2022-38177) By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. (CVE-2022-38178). ========================================================================== Ubuntu Security Notice USN-5332-1 March 17, 2022 bind9 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 21.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS Summary: Several security issues were fixed in Bind. Software Description: - bind9: Internet Domain Name Server Details: Xiang Li, Baojun Liu, Chaoyi Lu, and Changgen Zou discovered that Bind incorrectly handled certain bogus NS records when using forwarders. A remote attacker could possibly use this issue to manipulate cache results. (CVE-2021-25220) It was discovered that Bind incorrectly handled certain crafted TCP streams. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service. This issue only affected Ubuntu 21.10. (CVE-2022-0396) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 21.10: bind9 1:9.16.15-1ubuntu1.2 Ubuntu 20.04 LTS: bind9 1:9.16.1-0ubuntu2.10 Ubuntu 18.04 LTS: bind9 1:9.11.3+dfsg-1ubuntu1.17 In general, a standard system update will make all the necessary changes. For the oldstable distribution (buster), this problem has been fixed in version 1:9.11.5.P4+dfsg-5.1+deb10u7. For the stable distribution (bullseye), this problem has been fixed in version 1:9.16.27-1~deb11u1. We recommend that you upgrade your bind9 packages. For the detailed security status of bind9 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/bind9 Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEtuYvPRKsOElcDakFEMKTtsN8TjYFAmI010UACgkQEMKTtsN8 Tjbp3xAAil38qfAIdNkaIxY2bauvTyZDWzr6KUjph0vzmLEoAFQ3bysVSGlCnZk9 IgdyfPRWQ+Bjau1/dlhNYaTlnQajbeyvCXfJcjRRgtUDCp7abZcOcb1WDu8jWLGW iRtKsvKKrTKkIou5LgDlyqZyf6OzjgRdwtm86GDPQiCaSEpmbRt+APj5tkIA9R1G ELWuZsjbIraBU0TsNfOalgNpAWtSBayxKtWB69J8rxUV69JI194A4AJ0wm9SPpFV G/TzlyHp1dUZJRLNmZOZU/dq4pPsXzh9I4QCg1kJWsVHe2ycAJKho6hr5iy43fNl MuokfI9YnU6/9SjHrQAWp1X/6MYCR8NieJ933W89/Zb8eTjTZC8EQGo6fkA287G8 glQOrJHMQyV+b97lT67+ioTHNzTEBXTih7ZDeC1TlLqypCNYhRF/ll0Hx/oeiJFU rbjh2Og9huhD5JH8z8YAvY2g81e7KdPxazuKJnQpxGutqddCuwBvyI9fovYrah9W bYD6rskLZM2x90RI2LszHisl6FV5k37PaczamlRqGgbbMb9YlnDFjJUbM8rZZgD4 +8u/AkHq2+11pTtZ40NYt1gpdidmIC/gzzha2TfZCHMs44KPMMdH+Fid1Kc6/Cq8 QygtL4M387J9HXUrlN7NDUOrDVuVqfBG+ve3i9GCZzYjwtajTAQ= =6st2 -----END PGP SIGNATURE----- . 8) - aarch64, ppc64le, s390x, x86_64 3. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: bind security update Advisory ID: RHSA-2023:0402-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2023:0402 Issue date: 2023-01-24 CVE Names: CVE-2021-25220 CVE-2022-2795 ==================================================================== 1.
