  - 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.

  - 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)
