High
Description:
以下項目について対処しました。
[Security Fix]
- mod_auth_openidc の AES GCM 復号化処理には、JSON Web Encryption
形式のデータから取得した認証タグの長さを誤って処理してしまう問題が
あるため、リモートの攻撃者により、細工された認証タグを介して、JSON
Web Encryption 形式のデータの改竄を可能とする脆弱性が存在します。

Stream name: 2.3
解決策:
パッケージをアップデートしてください。
CVE:
CVE-2023-37464
OpenIDC/cjose is a C library implementing the Javascript Object Signing and Encryption (JOSE). The AES GCM decryption routine incorrectly uses the Tag length from the actual Authentication Tag provided in the JWE. The spec says that a fixed length of 16 octets must be applied. Therefore this bug allows an attacker to provide a truncated Authentication Tag and to modify the JWE accordingly. Users should upgrade to a version >= 0.6.2.2. Users unable to upgrade should avoid using AES GCM encryption and replace it with another encryption algorithm (e.g. AES CBC).
