Affected: AlmaLinux:9: mod_auth_openidc

The mod_auth_openidc is an OpenID Connect authentication module for Apache HTTP Server. It enables an Apache HTTP Server to operate as an OpenID Connect Relying Party and/or OAuth 2.0 Resource Server.

Security Fix(es):

* mod_auth_openidc: Open Redirect in oidc_validate_redirect_url() using tab character (CVE-2022-23527) * mod_auth_openidc: NULL pointer dereference when OIDCStripCookies is set and a crafted Cookie header is supplied (CVE-2023-28625)

Additional Changes:

For detailed information on changes in this release, see the AlmaLinux Release Notes linked from the References section.

mod_auth_openidc is an OpenID Certified™ authentication and authorization module for the Apache 2.x HTTP server. Versions prior to 2.4.12.2 are vulnerable to Open Redirect. When providing a logout parameter to the redirect URI, the existing code in oidc_validate_redirect_url() does not properly check for URLs that start with /\t, leading to an open redirect. This issue has been patched in version 2.4.12.2. Users unable to upgrade can mitigate the issue by configuring mod_auth_openidc to only allow redirection when the destination matches a given regular expression with OIDCRedirectURLsAllowed.

Affected: openEuler:22.03-LTS: mod_auth_openidc

This module enables an Apache 2.x web server to operate as an OpenID Connect Relying Party(RP) to an OpenID Connect Provider(OP). Security Fix(es): mod_auth_openidc is an OpenID Certified™ authentication and authorization module for the Apache 2.x HTTP server. Versions prior to 2.4.12.2 are vulnerable to Open Redirect. When providing a logout parameter to the redirect URI, the existing code in oidc_validate_redirect_url() does not properly check for URLs that start with /\t, leading to an open redirect. This issue has been patched in version 2.4.12.2. Users unable to upgrade can mitigate the issue by configuring mod_auth_openidc to only allow redirection when the destination matches a given regular expression with OIDCRedirectURLsAllowed.(CVE-2022-23527) mod_auth_openidc is an authentication and authorization module for the Apache 2.x HTTP server that implements the OpenID Connect Relying Party functionality. In versions 2.0.0 through 2.4.13.1, when `OIDCStripCookies` is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using `OIDCStripCookies`.(CVE-2023-28625)
