語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，廠商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。- FreeIPA ipa-otpd 精靈的 OAuth2 裝置授權處理常式中的兩個差一錯誤，在處理來自已設定的外部 OAuth2/OIDC 身分識別提供者的過大回應時，可能會導致越界記憶體存取。控制或可以攻擊 IdP 端點的攻擊者可能能夠觸發 ipa-otpd 寫入或讀取固定大小緩衝區末端一個位元組。利用需要為 FreeIPA 設定外部 IdP、攻擊者控制或該 IdP 的 MITM，以及使用者才能啟動 OAuth2 裝置授權流程。最可能的影響是影響 ipa-otpd 精靈的有限拒絕服務。（CVE-2026-14612）
請注意，Nessus 的判定取決於廠商所報告的套件是否存在。
