Ubuntu 20.04 LTS / 21.04:Linux 内核漏洞 (USN-5046-1)

high Nessus 插件 ID 152665

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-5046-1 公告中提及的多个漏洞的影响。

- Bluetooth 核心规范 2.1 至 5.2 中的 Bluetooth LE 和 BR/EDR 安全配对可能允许附近的中间人攻击者在配对期间(在密钥身份验证过程中)通过反射发起设备的公钥和身份验证证据来识别所使用的密钥,从而可能允许该攻击者使用配对会话的正确密钥与响应设备完成经过身份验证的配对。此攻击方法一次确定密码值的一位。(CVE-2020-26558)

- BlueZ 中存在访问控制不当,经过身份验证的用户可利用此漏洞,通过邻近访问可能造成信息泄露。(CVE-2021-0129)

- 在用户连接恶意 HCI TTY 蓝牙设备的方式中,发现 Linux 内核 HCI 设备初始化子系统中存在双重释放内存损坏缺陷。本地用户可利用此缺陷导致系统崩溃。此缺陷影响从 3.13 开始的所有 Linux 内核版本。(CVE-2021-3564)

- 在用户调用 ioct HCIUNBLOCKADDR 的方式或触发调用 hci_unregister_dev() 及 hci_sock_blacklist_add()、hci_sock_blacklist_del()、hci_get_conn_info()、hci_get_auth_info() 调用之一的争用条件的方式中,发现 Linux 内核 HCI 子系统的 hci_sock_bound_ioctl() 函数中存在释放后使用漏洞。特权本地用户可利用此缺陷造成系统崩溃,或提升其在系统中的特权。此缺陷影响 5.13-rc5 之前的 Linux 内核版本。(CVE-2021-3573)

- ** 拒绝 ** 请勿使用此候选编号。ConsultIDs:CVE-2021-38208。原因:此候选版本是 CVE-2021-38208 的保留复本。注意:所有 CVE 用户都应该参照 CVE-2021-38208 而非此候选版本。为防止意外使用,本候选中的所有引用和描述都已被删除。(CVE-2021-3587)

- 客户端在 Linux xen-netback 中触发释放后使用。恶意或有缺陷的网络 PV 前端可强制 Linux netback 禁用接口,并终止与队列 0 相关的接收内核线程,以响应前端发送畸形数据包。后端遭到破坏时,此类内核线程终止将导致 Linux netback 中发生释放后使用,这是因为与队列 0 相关的内核线程已经退出,因此对过时指针执行 kthread_stop 调用。
(CVE-2021-28691)

请注意,Nessus 尚未测试此问题,而是只依赖于应用程序自我报告的版本号。

解决方案
