Ubuntu 20.04 LTS / 21.04:Linux 内核漏洞 (USN-5161-1)

high Nessus 插件 ID 155752

简介

远程 Ubuntu 主机缺少一个或多个安全更新。

描述

远程 Ubuntu 20.04 LTS / 21.04 主机上安装的程序包受到 USN-5161-1 公告中提及的多个漏洞的影响。

- 在版本低于 5.14.6 的 Linux 内核中,在 drivers/soc/aspeed/aspeed-lpc-ctrl.c 的 aspeed_lpc_ctrl_mmap 中发现一个问题。能够访问 Aspeed LPC 控制接口的本地攻击者可覆盖内核中的内存并可能执行权限,即 CID-b49a0e69a7b1。这是某个比较使用非内存大小值所致。(CVE-2021-42252)

- 在 v5.14-rc1 之前版本的 Linux 内核中发现一个漏洞。入站 SCTP 数据包缺少大小验证可能会允许内核读取未初始化的内存。(CVE-2021-3655)

- 在 Linux 内核的 drivers/crypto/ccp/ccp-ops.c 的 ccp_run_aes_gcm_cmd() 函数中发现一个内存泄漏缺陷,攻击者可利用此缺陷造成拒绝服务(内存消耗)。
此缺陷与较早版本的 CVE-2019-18808 类似。(CVE-2021-3744)

请注意,Nessus 尚未测试此问题,而是只依靠应用程序自我报告的版本号来判断。

解决方案

更新受影响的程序包。
