Summary
Red Hat Security Advisory: Red Hat Single Sign-On 7.6.7 security update on RHEL 8
Notes
Topic
New Red Hat Single Sign-On 7.6.7 packages are now available 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.
Details
Red Hat Single Sign-On 7.6 is a standalone server, based on the Keycloak project, that provides authentication and standards-based single sign-on capabilities for web and mobile applications.
This release of Red Hat Single Sign-On 7.6.7 on RHEL 8 serves as a replacement for Red Hat Single Sign-On 7.6.6, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.
Security Fix(es):
* redirect_uri validation logic that allows for a bypass of otherwise explicitly allowed hosts (CVE-2023-6291)
* guava: insecure temporary directory creation (CVE-2023-2976)
* jetty-server: OutOfMemoryError for large multipart without filename read via request.getParameter() (CVE-2023-26048)
* jetty-server: Cookie parsing of quoted values can exfiltrate values from other cookies (CVE-2023-26049)
* reflected XSS via wildcard in OIDC redirect_uri (CVE-2023-6134)
* open redirect via "form_post.jwt" JARM response mode (CVE-2023-6927)
* santuario: Private Key disclosure in debug-log output (CVE-2023-44483)
* Log Injection during WebAuthn authentication or registration (CVE-2023-6484)3-44483)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Summary
Red Hat Security Advisory: Red Hat build of Keycloak 22.0.7 images enhancement and security update
Notes
Topic
A security update is now available for Red Hat build of Keycloak 22.0.7 images running on OpenShift Container Platform.
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.
Details
Red Hat build of Keycloak 22.0.7 is an integrated solution, available as a Red Hat JBoss Middleware for OpenShift containerized image, based on the Keycloak project, that provides authentication and standards-based single sign-on capabilities for web and mobile applications.
This erratum releases a security update and enhancement images for Red Hat build of Keycloak 22.0.7 for use within the OpenShift Container Platform 4.12, 4.13 and 4.14 cloud computing Platform-as-a-Service (PaaS) for on-premise or private cloud deployments, aligning with the standalone product release.
Security Fix(es):
* reflected XSS via wildcard in OIDC redirect_uri (CVE-2023-6291)
* redirect_uri validation logic that allows for a bypass of otherwise explicitly allowed hosts (CVE-2023-6134)
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.

Summary
Red Hat Security Advisory: Red Hat Single Sign-On 7.6.6 for OpenShift image enhancement and security update
Notes
Topic
A new image is available for Red Hat Single Sign-On 7.6.6, running on OpenShift Container Platform 3.10 and 3.11, and 4.3.
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.
Details
Red Hat Single Sign-On is an integrated sign-on solution, available as a Red Hat JBoss Middleware for OpenShift containerized image. The Red Hat Single Sign-On for OpenShift image provides an authentication server that you can use to log in centrally, log out, and register. You can also manage user accounts for web applications, mobile applications, and RESTful web services.
This erratum releases a new image for Red Hat Single Sign-On 7.6.6 for use within the OpenShift Container Platform 3.10, OpenShift Container Platform 3.11, and OpenShift Container Platform 4.3 cloud computing Platform-as-a-Service (PaaS) for on-premise or private cloud deployments, aligning with the standalone product release.
Security Fix(es):
* keycloak: redirect_uri validation logic that allows for a bypass of otherwise explicitly allowed hosts (CVE-2023-6134)
* keycloak: reflected XSS via wildcard in OIDC redirect_uri (CVE-2023-6291)
* keycloak: offline session token DoS (CVE-2023-6563)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Summary
Red Hat Security Advisory: Red Hat Single Sign-On 7.6.7 for OpenShift image enhancement update
Notes
Topic
A new image is available for Red Hat Single Sign-On 7.6.7, running on OpenShift Container Platform 3.10 and 3.11, and 4.3.
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.
Details
Red Hat Single Sign-On is an integrated sign-on solution, available as a
Red Hat JBoss Middleware for OpenShift containerized image. The Red Hat
Single Sign-On for OpenShift image provides an authentication server that
you can use to log in centrally, log out, and register. You can also manage
user accounts for web applications, mobile applications, and RESTful web
services.
Security Fix(es):
* redirect_uri validation logic that allows for a bypass of otherwise explicitly allowed hosts (CVE-2023-6291)
* guava: insecure temporary directory creation (CVE-2023-2976)
* jetty-server: OutOfMemoryError for large multipart without filename read via request.getParameter() (CVE-2023-26048)
* jetty-server: Cookie parsing of quoted values can exfiltrate values from other cookies (CVE-2023-26049)
* reflected XSS via wildcard in OIDC redirect_uri (CVE-2023-6134)
* open redirect via "form_post.jwt" JARM response mode (CVE-2023-6927)
* santuario: Private Key disclosure in debug-log output (CVE-2023-44483)
* Log Injection during WebAuthn authentication or registration (CVE-2023-6484)
This erratum releases a new image for Red Hat Single Sign-On 7.6.7 for use within the OpenShift Container Platform 3.10, OpenShift Container Platform
3.11, and within the OpenShift Container Platform 4.3 cloud computing Platform-as-a-Service (PaaS) for on-premise or private cloud deployments, aligning with the standalone product release.

Notes
Topic
New Red Hat Single Sign-On 7.6.7 packages are now available for Red Hat Enterprise Linux 7.
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.
Details
Red Hat Single Sign-On 7.6 is a standalone server, based on the Keycloak project, that provides authentication and standards-based single sign-on capabilities for web and mobile applications.
This release of Red Hat Single Sign-On 7.6.7 on RHEL 7 serves as a replacement for Red Hat Single Sign-On 7.6.6, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.
Security Fix(es):
* redirect_uri validation logic that allows for a bypass of otherwise explicitly allowed hosts (CVE-2023-6291)
* guava: insecure temporary directory creation (CVE-2023-2976)
* jetty-server: OutOfMemoryError for large multipart without filename read via request.getParameter() (CVE-2023-26048)
* jetty-server: Cookie parsing of quoted values can exfiltrate values from other cookies (CVE-2023-26049)
* reflected XSS via wildcard in OIDC redirect_uri (CVE-2023-6134)
* open redirect via "form_post.jwt" JARM response mode (CVE-2023-6927)
* santuario: Private Key disclosure in debug-log output (CVE-2023-44483)

Red Hat Security Advisory: Red Hat Single Sign-On 7.6.7 security update on RHEL 9
Notes
Topic
New Red Hat Single Sign-On 7.6.7 packages are now available for Red Hat Enterprise Linux 9.
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.
Details
Red Hat Single Sign-On 7.6 is a standalone server, based on the Keycloak project, that provides authentication and standards-based single sign-on capabilities for web and mobile applications.
This release of Red Hat Single Sign-On 7.6.7 on RHEL 9 serves as a replacement for Red Hat Single Sign-On 7.6.6, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.
Security Fix(es):
* redirect_uri validation logic that allows for a bypass of otherwise explicitly allowed hosts (CVE-2023-6291)
* guava: insecure temporary directory creation (CVE-2023-2976)
* jetty-server: OutOfMemoryError for large multipart without filename read via request.getParameter() (CVE-2023-26048)
* jetty-server: Cookie parsing of quoted values can exfiltrate values from other cookies (CVE-2023-26049)
* reflected XSS via wildcard in OIDC redirect_uri (CVE-2023-6134)
* open redirect via "form_post.jwt" JARM response mode (CVE-2023-6927)
* santuario: Private Key disclosure in debug-log output (CVE-2023-44483)
* Log Injection during WebAuthn authentication or registration (CVE-2023-6484)
