Updated apache-mod_auth_openidc packages fix security vulnerability
Publication date: 02 Oct 2021Modification date: 02 Oct 2021
Type: security
Affected Mageia releases : 8
CVE: CVE-2021-32786 , CVE-2021-32791 , CVE-2021-32792 , CVE-2021-32785
Description
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. (CVE-2021-32786)
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.
(CVE-2021-32791)
In mod_auth_openidc before version 2.4.9, there is an XSS vulnerability in
when using `OIDCPreservePost On`. (CVE-2021-32792)
