    Rebase to 2.4.13.2 version, fix CVE-2023-28625

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:6940 advisory.

    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)

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3409 advisory.

  - A flaw was found in mod_auth_openidc before version 2.4.1. An open redirect issue exists in URLs with a     slash and backslash at the beginning. (CVE-2019-20479)

  - mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions     as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. When     mod_auth_openidc versions prior to 2.4.9 are configured to use an unencrypted Redis cache     (`OIDCCacheEncrypt off`, `OIDCSessionType server-cache`, `OIDCCacheType redis`), `mod_auth_openidc`     wrongly performed argument interpolation before passing Redis requests to `hiredis`, which would perform     it again and lead to an uncontrolled format string bug. Initial assessment shows that this bug does not     appear to allow gaining arbitrary code execution, but can reliably provoke a denial of service by     repeatedly crashing the Apache workers. This bug has been corrected in version 2.4.9 by performing     argument interpolation only once, using the `hiredis` API. As a workaround, this vulnerability can be     mitigated by setting `OIDCCacheEncrypt` to `on`, as cache keys are cryptographically hashed before use     when this option is enabled. (CVE-2021-32785)

  - mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions     as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In versions     prior to 2.4.9, `oidc_validate_redirect_url()` does not parse URLs the same way as most browsers do. As a     result, this function can be bypassed and leads to an Open Redirect vulnerability in the logout     functionality. This bug has been fixed in version 2.4.9 by replacing any backslash of the URL to redirect     with slashes to address a particular breaking change between the different specifications (RFC2396 /     RFC3986 and WHATWG). As a workaround, this vulnerability can be mitigated by configuring     `mod_auth_openidc` to only allow redirection whose destination matches a given regular expression.
    (CVE-2021-32786)

  - mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions     as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In     mod_auth_openidc before version 2.4.9, the AES GCM encryption in mod_auth_openidc uses a static IV and     AAD. It is important to fix because this creates a static nonce and since aes-gcm is a stream cipher, this     can lead to known cryptographic issues, since the same key is being reused. From 2.4.9 onwards this has     been patched to use dynamic values through usage of cjose AES encryption routines. (CVE-2021-32791)

  - mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions     as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In     mod_auth_openidc before version 2.4.9, there is an XSS vulnerability in when using `OIDCPreservePost On`.
    (CVE-2021-32792)

  - 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)
