1.修復(fù)的CVE ·CVE-2021-28041 描述：OpenSSH（OpenBSD Secure Shell）是Openbsd計(jì)劃組的一套用于安全訪問遠(yuǎn)程計(jì)算機(jī)的連接工具。該工具是SSH協(xié)議的開源實(shí)現(xiàn)，支持對所有的傳輸進(jìn)行加密，可有效阻止竊聽、連接劫持以及其他網(wǎng)絡(luò)級的攻擊。OpenSSH中的ssh代理具有雙重釋放內(nèi)存損壞漏洞，更具體地說是在ssh-agent應(yīng)用程序中。此漏洞使有權(quán)訪問代理套接字的攻擊者可以將代理轉(zhuǎn)發(fā)到與惡意用戶共享的帳戶，也可以轉(zhuǎn)發(fā)給具有根訪問權(quán)限的攻擊者的主機(jī)。此漏洞帶來的最大威脅是機(jī)密性，完整性和系統(tǒng)可用性。
