Ubuntu 20.04 LTS/21.04:Linux 核心弱點 (USN-5046-1)

high Nessus Plugin ID 152665

Synopsis

遠端 Ubuntu 主機缺少一個或多個安全性更新。

描述

遠端 Ubuntu 20.04 LTS / 21.04 主機上安裝的多個套件受到 USN-5046-1 公告中所提及的多個弱點影響。

- 藍牙核心規格 2.1 到 5.2 中的 Bluetooth LE 和 BR/EDR 安全配對可能允許附近的攔截式攻擊者透過公開金鑰的反映,識別配對期間 (在 Passkey 驗證程序中) 所使用的 Passkey 以及起始裝置的驗證證據,可能允許此攻擊者使用配對工作階段的正確 Passkey,完成與回應裝置的驗證配對。攻擊方法會以一次一位元的方式來判斷 Passkey 值。(CVE-2020-26558)

- BlueZ 中的不當存取控制可能會允許經驗證的使用者透過相鄰存取造成資訊洩漏。(CVE-2021-0129)

- 在使用者附加惡意 HCI TTY 藍牙裝置的方式中,發現 Linux 核心 HCI 裝置初始化子系統中存在一個重複釋放記憶體損毀缺陷。本機使用者可能會利用此缺陷造成系統當機。此缺陷會影響從 3.13 開始的所有 Linux 核心版本。(CVE-2021-3564)

- 在使用者呼叫 ioct HCIUNBLOCKADDR 的方式中,或是其他觸發呼叫 hci_unregister_dev() 以及呼叫 hci_sock_blacklist_add()、hci_sock_blacklist_del()、hci_get_conn_info()、hci_get_auth_info() 之一的爭用情形的方式中,發現 Linux 核心 HCI 子系統的 hci_sock_bound_ioctl() 函式中存在釋放後使用問題。有權限的本機使用者可利用此缺陷來損毀系統或提高自己的系統權限。此缺陷會影響 5.13-rc5 之前的 Linux 核心版本。(CVE-2021-3573)

- ** 拒絕 ** 請勿使用此候選版本編號。ConsultIDs:CVE-2021-38208。原因:此候選編號是 CVE-2021-38208 的保留複本。注意:所有 CVE 使用者都應該參照 CVE-2021-38208 而非此候選編號。已移除此候選版本中的所有參照和描述,以防止意外使用。(CVE-2021-3587)

- 來賓在 Linux xen-netback 中觸發釋放後使用惡意或錯誤的網路 PV 前端可強制 Linux netback 停用介面,並終止與佇列 0 相關的接收核心執行緒,以回應前端傳送格式錯誤的封包。這類核心執行緒會在後端損毀時導致 Linux netback 中出現釋放後使用情形,因為與佇列 0 相關的核心執行緒已經已結束,因此將針對過時指標執行 kthread_stop 呼叫。
(CVE-2021-28691)

請注意,Nessus 並未測試此問題,而是僅依據應用程式自我報告的版本號碼。
