1. 修复的CVE CVE-2021-4122 Cryptsetup是一个实用程序，用于基于DMCrypt内核模块方便地设置磁盘加密。 cryptsetup 存在安全漏洞，该漏洞源于软件对于数据真实性缺乏有效的验证。一个特别制作的LUKS头可以欺骗cryptsetup在设备恢复期间禁用加密。物理访问介质(如闪存盘)的攻击者可以利用这个漏洞迫使用户永久禁用该介质的加密层。 2. 受影响的操作系统及软件包 ·银河麒麟桌面操作系统V10 SP1 x86_64 架构： cryptsetup-bin、cryptsetup-initramfs、cryptsetup-run、cryptsetup、libcryptsetup12 arm64 架构： cryptsetup-bin、cryptsetup-initramfs、cryptsetup-run、cryptsetup、libcryptsetup12 mips64el 架构： cryptsetup-bin、cryptsetup-initramfs、cryptsetup-run、cryptsetup、libcryptsetup12 loongarch64 架构： cryptsetup-bin、cryptsetup-initramfs、cryptsetup-run、cryptsetup、libcryptsetup12 3. 软件包修复版本 ·银河麒麟桌面操作系统V10 SP1 2:2.2.2-3kylin2.4k0.4 4. 修复方法 方法一：升级安装 执行更新命令进行升级 $sudo apt update $sudo apt install cryptsetup 方法二：下载软件包进行升级安装 通过软件包地址下载软件包，使用软件包升级命令根据受影响的软件包列表升级相关的组件包。 $sudo dpkg -i /Path1/Package1 /Path2/Package2 /Path3/Package3…… 注：Path 指软件包下载到本地的路径，Package指下载的软件包名称，多个软件包则以空格分开。 5. 软件包下载地址 银河麒麟桌面操作系统V10 SP1 x86_64软件包下载地址 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软件包下载地址 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软件包下载地址 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软件包下载地址 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. 修复验证 使用软件包查询命令，查看相关的软件包版本大于或等于修复版本则成功修复。 $sudo dpkg -l |grep Package 注：Package为软件包包名。
