Ubuntu 14.04 LTS：Mono 弱點 (USN-2547-1)

critical Nessus Plugin ID 82074

語系：

概要

遠端 Ubuntu 主機缺少一個或多個安全性更新。

說明

據發現，Mono TLS 實作容易受到 SKIP-TLS 弱點影響。遠端攻擊者可能利用此問題發動用戶端模擬攻擊。(CVE-2015-2318)

據發現，Mono TLS 實作容易受到 FREAK 弱點影響。遠端攻擊者或攔截式攻擊者可能利用此問題強制使用不安全的加密套件。(CVE-2015-2319)

據發現，Mono TLS 實作仍然支援遞補至 SSLv2。此更新已移除該功能，因為已知 SSLv2 的使用不安全。(CVE-2015-2320)

據發現，Mono 在某些情況下並未正確處理記憶體。遠端攻擊者可能利用此問題造成 Mono 損毀，進而導致拒絕服務或取得敏感資訊。此問題僅適用 Ubuntu 12.04 LTS。
(CVE-2011-0992)

據發現，Mono 並未正確處理雜湊衝突。遠端攻擊者可能利用此問題造成 Mono 損毀，進而導致拒絕服務。此問題僅適用 Ubuntu 12.04 LTS。(CVE-2012-3543)

請注意，Tenable Network Security 已直接從 Ubuntu 安全性公告擷取前述描述區塊。Tenable 已盡量在不造成其他問題的前提下，嘗試自動清理並將其格式化。
