Vulnerability from variot

In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 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. runc is a CLI (command line interface) tool for building and running containers according to the OCI specification. BIND 9.0.0 to 9.11.21, 9.12.0 to 9.16.5, 9.17.0 to 9.17.3, 9.9.3-S1 to 9.11.21-S1 have security vulnerabilities, attackers can construct a special request to cause an assertion failure Causes the target service to end abnormally. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.

This advisory contains the container images for Red Hat OpenShift Container Platform 4.5.20. See the following advisory for the RPM packages for this release:

https://access.redhat.com/errata/RHSA-2020:5119

Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes:

https://docs.openshift.com/container-platform/4.5/release_notes/ocp-4-5-rel ease-notes.html

This update fixes the following bug among others:

Previously, the Prometheus swagger definition contained a $ref property which could not be resolved. This caused a runtime error to occur when using the Prometheus operand creation form. This was fixed by adding a definitions property to schema returned by the definitionFor helper function so that the $ref property can resolve. There are no longer runtime errors when using the Prometheus operand creation form. (BZ#1885228)

Description:\n\nRed Hat OpenShift Container Platform is Red Hat\u0027s cloud computing\nKubernetes application platform solution designed for on-premise or private\ncloud deployments. \n\nThis advisory contains the container images for Red Hat OpenShift Container\nPlatform 4.5.20. See the following advisory for the RPM packages for this\nrelease:\n\nhttps://access.redhat.com/errata/RHSA-2020:5119\n\nSpace precludes documenting all of the container images in this advisory. \nSee the following Release Notes documentation, which will be updated\nshortly for this release, for details about these changes:\n\nhttps://docs.openshift.com/container-platform/4.5/release_notes/ocp-4-5-rel\nease-notes.html\n\nThis update fixes the following bug among others:\n\n* Previously, the Prometheus swagger definition contained a `$ref` property\nwhich could not be resolved. This caused a runtime error to occur when\nusing the Prometheus operand creation form. This was fixed by adding a\n`definitions` property to schema returned by the `definitionFor` helper\nfunction so that the `$ref` property can resolve. There are no longer\nruntime errors when using the Prometheus operand creation form. \n(BZ#1885228)\n\nYou may download the oc tool and use it to inspect release image metadata\nas follows:\n\n(For x86_64 architecture)\n\n  $ oc adm release info\nquay.io/openshift-release-dev/ocp-release:4.5.20-x86_64\n\nThe image digest is\nsha256:78b878986d2d0af6037d637aa63e7b6f80fc8f17d0f0d5b077ac6aca83f792a0\n\n(For s390x architecture)\n\n  $ oc adm release info\nquay.io/openshift-release-dev/ocp-release:4.5.20-s390x\n\nThe image digest is\nsha256:372d9aea634d36704d8500a2f940edb3867bfde14c0e5aa19534ea5ac90083d4\n\n(For ppc64le architecture)\n\n  $ oc adm release info\nquay.io/openshift-release-dev/ocp-release:4.5.20-ppc64le\n\nThe image digest is\nsha256:030d8323cce90de6bc7ad4119ebb7f000bde06e742f6923faf76707ffe85634a\n\nAll OpenShift Container Platform 4.5 users are advised to upgrade to these\nupdated packages and images when they are available in the appropriate\nrelease channel.

A remote attacker could possibly use this issue to cause Bind to\ncrash, resulting in a denial of service. This issue only affected Ubuntu\n20.04 LTS. (CVE-2020-8620)\n\nJoseph Gullo discovered that Bind incorrectly handled QNAME minimization\nwhen used in certain configurations. A remote attacker could possibly use\nthis issue to cause Bind to crash, resulting in a denial of service. This\nissue only affected Ubuntu 20.04 LTS. (CVE-2020-8621)\n\nDave Feldman, Jeff Warren, and Joel Cunningham discovered that Bind\nincorrectly handled certain truncated responses to a TSIG-signed request. A\nremote attacker could possibly use this issue to cause Bind to crash,\nresulting in a denial of service. (CVE-2020-8622)\n\nLyu Chiy discovered that Bind incorrectly handled certain queries. A remote\nattacker could possibly use this issue to cause Bind to crash, resulting in\na denial of service. (CVE-2020-8623)\n\nJoop Boonen discovered that Bind incorrectly handled certain subdomain\nupdate-policy rules. A remote attacker granted privileges to change certain\nparts of a zone could use this issue to change other contents of the zone,\ncontrary to expectations. This issue only affected Ubuntu 18.04 LTS and\nUbuntu 20.04 LTS. (CVE-2020-8624)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 20.04 LTS:\n  bind9                           1:9.16.1-0ubuntu2.3\n\nUbuntu 18.04 LTS:\n  bind9                           1:9.11.3+dfsg-1ubuntu1.13\n\nUbuntu 16.04 LTS:\n  bind9                           1:9.10.3.dfsg.P4-8ubuntu1.17\n\nIn general, a standard system update will make all the necessary changes. \n\nFor the stable distribution (buster), these problems have been fixed in\nversion 1:9.11.5.P4+dfsg-5.1+deb10u2. \n\nWe recommend that you upgrade your bind9 packages. \n\nFor the detailed security status of bind9 please refer to its security\ntracker page at:\nhttps://security-tracker.debian.org/tracker/bind9\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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\nSx85bc7+6f1daR04r5ay/mCuWPTQYrM1VyBsFnAvGxWoznHnmbk=\n=kUyE\n-----END PGP SIGNATURE-----\n",
