SSL：沒有替代憑證使用者名稱符合 |新發布的CURL(USN-6237-1)帶來痛苦

自 CURL 新版本發布以來https://ubuntu.com/security/notices/USN-6237-1我們在 Ubuntu 上使用 curl 命令時遇到了問題：

sudo apt update -y && sudo apt install --no-install-recommends -y curl
curl -vvv https://downloads.apache.org/maven/maven-3/3.8.8/binaries/

錯誤：

如何修復它？我們現在應該以某種方式控制第三方憑證嗎？先致謝

看起來有一個損壞的向後端口用於安全修復。應該在 7.81.0-1ubuntu1.13 中修復，該版本修復了 7.81.0-1ubuntu1.11。從https://launchpad.net/ubuntu/jammy/+source/curl/+changelog:

curl (7.81.0-1ubuntu1.13) jammy-security; urgency=medium

  * SECURITY REGRESSION: broken ssl cert wildcard handling (LP: #2028170)
    - debian/patches/CVE-2023-28321.patch: fix missing line in backport.

取得舊版的方法：

刪除它並用於apt安裝先前的版本。以下是 AU 上最活躍的話題：如何透過 apt-get 降級軟體包？也可以從來源安裝。這可能是更好的方法：您可以保留 apt 版本不變，等待更新/錯誤修復，然後在來源安裝版本旁邊嘗試新版本。

檢查這些是否可以解決您的問題。如果是這樣，請提交錯誤報告。如果你想堅持使用舊的 apt 版本別針包裹

答案3

這是一個已確認的錯誤：https://bugs.launchpad.net/ubuntu/+source/curl/+bug/2028170

他們已經透過恢復變更修復了該問題，新的軟體包版本很快就會上線。
