TITLE

Debian Security Advisory 4807-1

DESCRIPTION

The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified. OpenSSL's s_server, s_client and verify tools have support for the "-crl_download" option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue. Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). The product supports a variety of encryption algorithms, including symmetric ciphers, hash algorithms, secure hash algorithms, etc. For the detailed security status of openssl please refer to its security tracker page at: https://security-tracker.debian.org/tracker/openssl 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----- iQKTBAEBCgB9FiEERkRAmAjBceBVMd3uBUy48xNDz0QFAl/PmNRfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDQ2 NDQ0MDk4MDhDMTcxRTA1NTMxRERFRTA1NENCOEYzMTM0M0NGNDQACgkQBUy48xND z0SrxA//cDd0JVO9bdkBLrjg3bh2ibaL7rZxWM2kDOZxQ9dTyuNKHXpk72EQN7bo YzYUOphu8Pea/v2E2bA0VzKka56lu1zmA1r2xXyZoK3YWoyVAdQe/AbrsNZh+k5U iZ9U5VeBNmb78vZqalFnecZBAhmPBmFKmE4yc7qhj+G1XGO+/yuRL8sBGpK3WKDX dj31X8+YlEfidj9LKj0mER1XpjaE7soWnmlFA8vI/cjBLnvWo4MyXUbicW2r028C KB/ACbp5BzXiZkcv45Dmk73Wp2GtMPamF3iL6VBNkEy5cBXvvD+WQCJLr87w+zHr Abvfz8UXvJnsD/qP7nEuQkMBDiZPeCIOe1lGtiNtU0oeDn1i9akVZ3pEtOf3azJ+ ZQRrxPY+qwWRenuf2CLBUzIzWh+9wUy3ZIOxSycBoqn1xN//EaZ38PNLpiYl2llM 1RyuvMn7jMo5Ow6keJ7ohIfY0FD3LNJId5Sf4EPfJHy/EAe/qSf+/WXXvLQAlMdg 0zkzBXSCHPlhOm4NgF+LuGqpyd10OK6O7C1eo2xejylohV1UJUXU+2CQfa2HQ0o4 eV5aYOsVEBPBIxedCd/XyVNCPrStetLhdP8kjASznPkIKcw1L7GW0SongEt6+7T+ csanRpBW+PoDRofOjop+zTAFesQLt/q7w2sjZCg2Wj/hEN6PeCs= =eV7T -----END PGP SIGNATURE----- . This issue was reported to OpenSSL on 9th November 2020 by David Benjamin (Google). Initial analysis was performed by David Benjamin with additional analysis by Matt Caswell (OpenSSL). The fix was developed by Matt Caswell. Note ==== OpenSSL 1.0.2 is out of support and no longer receiving public updates. References ========== URL for this Security Advisory: https://www.openssl.org/news/secadv/20201208.txt Note: the online version of the advisory may be updated with additional details over time. For details of OpenSSL severity classifications please see: https://www.openssl.org/policies/secpolicy.html . Description: 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 4.6.9. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHSA-2020:5615 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/4.6/release_notes/ocp-4-6-rel ease-notes.html This update fixes the following bugs among others: * Previously, pre-flight installer validation for OpenShift Container Platform on OpenStack was performed on the flavor metadata. This could prevent installations to flavors detected as `baremetal`, which might have the required capacity to complete the installation. This is usually caused by OpenStack administrators not setting the appropriate metadata on their bare metal flavors. Validations are now skipped on flavors detected as `baremetal`, to prevent incorrect failures from being reported. (BZ#1889416) * Previously, there was a broken link on the OperatorHub install page of the web console, which was intended to reference the cluster monitoring documentation. (BZ#1904600) You may download the oc tool and use it to inspect release image metadata as follows: (For x86_64 architecture) $ oc adm release info quay.io/openshift-release-dev/ocp-release:4.6.9-x86_64 The image digest is sha256:43d5c84169a4b3ff307c29d7374f6d69a707de15e9fa90ad352b432f77c0cead (For s390x architecture) $ oc adm release info quay.io/openshift-release-dev/ocp-release:4.6.9-s390x The image digest is sha256:3d77e9b0fd14a5c4d50995bbb17494a02f27a69f2ffa9771b29d112fe084699f (For ppc64le architecture) $ oc adm release info quay.io/openshift-release-dev/ocp-release:4.6.9-ppc64le The image digest is sha256:0975188e83f8688f97180b408a447b41f492ee35d1dacd43a826b14db7d486e5 All OpenShift Container Platform 4.6 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift Console or the CLI oc command.
