There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A flaw was found in Libsoup. The server-side digest authentication implementation in the
    SoupAuthDomainDigest class does not properly track issued nonces or enforce the required incrementing
    nonce-count (nc) attribute. This vulnerability allows a remote attacker to capture a single valid
    authentication header and replay it repeatedly. Consequently, the attacker can bypass authentication and
    gain unauthorized access to protected resources, impersonating the legitimate user. (CVE-2026-3099)

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 在 Libsoup 中發現一個瑕疵。SoupAuthDomainDigest 類別中的伺服器端摘要式驗證實作未正確追踪發出的 nonce 或強制執行所需的遞增 nonce-count (nc) 屬性。此弱點允許遠端攻擊者擷取單一有效驗證標頭並重複重播。因此攻擊者可繞過驗證並取得對受保護資源的未經授權存取權從而模擬合法使用者。 (CVE-2026-3099)

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 在 Libsoup 中发现一个缺陷。SoupAuthDomainDigest 类中的服务器端摘要式身份验证实现未正确跟踪已颁发的临时信息或强制执行所需的递增临时信息计数 (nc) 属性。此漏洞允许远程攻击者捕获单个有效的认证标头并反复重放。因此攻击者可冒充合法用户绕过认证并获得对受保护资源未经授权的访问权限。 (CVE-2026-3099)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - Libsoup に欠陥が見つかりました。SoupAuthDomainDigest クラスのサーバー側のダイジェスト認証の実装は、発行された nonce を適切に追跡したり、必要な incremental nonce-countnc属性を強制したりすることができません。この脆弱性により、リモートの攻撃者が、単一の有効な認証ヘッダーをキャプチャし、繰り返してリプレイする可能性があります。その結果、攻撃者は認証をバイパスして、保護されたリソースへの認証されていないアクセスを取得し、正当なユーザーになりすます可能性があります。CVE-2026-3099

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。
