Hi,
The following vulnerability was published for libapache2-mod-auth-openidc.
CVE-2021-32791[0]:
| 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
