以下項目について対処しました。
[Security Fix]
- GnuTLS は誤った暗号法をセッションチケットの暗号化に使用しており、
TLS サーバーは最初のキーローテーションまではアプリケーションから派生した
暗号化キーの代わりに誤ったデータを使用するため、TLS1.2 では機密性の喪失、
TLS 1.3では認証が回避される脆弱性があります。(CVE-2020-13777)
解決策:
パッケージをアップデートしてください。
CVE:
CVE-2020-13777
GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application.
