1. 修復的CVE CVE-2021-4122 Cryptsetup是一個實用程序，用于基于DMCrypt內核模塊方便地設置磁盤加密。 cryptsetup 存在安全漏洞，該漏洞源于軟件對于數據真實性缺乏有效的驗證。一個特別制作的LUKS頭可以欺騙cryptsetup在設備恢復期間禁用加密。物理訪問介質(如閃存盤)的攻擊者可以利用這個漏洞迫使用戶永久禁用該介質的加密層。 2. 受影響的操作系統及軟件包 ·銀河麒麟桌面操作系統V10 SP1 x86_64 架構： cryptsetup-bin、cryptsetup-initramfs、cryptsetup-run、cryptsetup、libcryptsetup12 arm64 架構： cryptsetup-bin、cryptsetup-initramfs、cryptsetup-run、cryptsetup、libcryptsetup12 mips64el 架構： cryptsetup-bin、cryptsetup-initramfs、cryptsetup-run、cryptsetup、libcryptsetup12 loongarch64 架構： cryptsetup-bin、cryptsetup-initramfs、cryptsetup-run、cryptsetup、libcryptsetup12 3. 軟件包修復版本 ·銀河麒麟桌面操作系統V10 SP1 2:2.2.2-3kylin2.4k0.4 4. 修復方法 方法一：升級安裝 執行更新命令進行升級 $sudo apt update $sudo apt install cryptsetup 方法二：下載軟件包進行升級安裝 通過軟件包地址下載軟件包，使用軟件包升級命令根據受影響的軟件包列表升級相關的組件包。 $sudo dpkg -i /Path1/Package1 /Path2/Package2 /Path3/Package3…… 注：Path 指軟件包下載到本地的路徑，Package指下載的軟件包名稱，多個軟件包則以空格分開。 5. 軟件包下載地址 銀河麒麟桌面操作系統V10 SP1 x86_64軟件包下載地址 https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-bin_2.2.2-3kylin2.4k0.4_amd64.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-initramfs_2.2.2-3kylin2.4k0.4_all.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-run_2.2.2-3kylin2.4k0.4_all.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup_2.2.2-3kylin2.4k0.4_amd64.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/libcryptsetup12_2.2.2-3kylin2.4k0.4_amd64.deb arm64軟件包下載地址 https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-bin_2.2.2-3kylin2.4k0.4_arm64.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-initramfs_2.2.2-3kylin2.4k0.4_all.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-run_2.2.2-3kylin2.4k0.4_all.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup_2.2.2-3kylin2.4k0.4_arm64.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/libcryptsetup12_2.2.2-3kylin2.4k0.4_arm64.deb mips64el軟件包下載地址 https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-bin_2.2.2-3kylin2.4k0.4_mips64el.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-initramfs_2.2.2-3kylin2.4k0.4_all.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-run_2.2.2-3kylin2.4k0.4_all.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup_2.2.2-3kylin2.4k0.4_mips64el.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/libcryptsetup12_2.2.2-3kylin2.4k0.4_mips64el.deb loongarch64軟件包下載地址 https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-bin_2.2.2-3kylin2.4k0.4_loongarch64.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-initramfs_2.2.2-3kylin2.4k0.4_all.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup-run_2.2.2-3kylin2.4k0.4_all.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/cryptsetup_2.2.2-3kylin2.4k0.4_loongarch64.deb https://archive.kylinos.cn/kylin/KYLIN-ALL/pool/main/c/cryptsetup/libcryptsetup12_2.2.2-3kylin2.4k0.4_loongarch64.deb 6. 修復驗證 使用軟件包查詢命令，查看相關的軟件包版本大于或等于修復版本則成功修復。 $sudo dpkg -l |grep Package 注：Package為軟件包包名。
