Synopsis

遠端 Ubuntu 主機缺少一個或多個安全性更新。

描述

遠端 Ubuntu 16.04 LTS/18.04 LTS 主機上安裝的套件受到 USN-5094-1 公告中所提及的多個弱點影響。

- 在 Linux 核心 5.14-rc3 之前版本的追蹤模組功能中,發現使用者追蹤環形緩衝區的特定方式中缺少 CPU 資源。僅取得特權的本機使用者 (藉由 CAP_SYS_ADMIN 功能 ) 可利用此缺陷來耗盡資源,進而引發拒絕服務。
(CVE-2021-3679)

- 在 Linux:KVM 中發現一個問題,這是由於對 KVM 中的 VM_IO|VM_PFNMAP vmas 處理不當造成。此問題可造成使用者繞過 RO 檢查,並導致頁面在 VMM 和來賓仍可存取時遭到釋放。這讓能夠啟動和控制 VM 的使用者可以讀取/寫入隨機的記憶體頁面,並可能導致本機權限提升。(CVE-2021-22543)

- 在 powerpc 平台上 5.13.5 版之前的 Linux 核心中,arch/powerpc/kvm/book3s_rtas.c 允許 KVM 來賓 OS 使用者透過 rtas_args.nargs 造成主機 OS 記憶體損毀,亦稱 CID-f62f3c20647e。(CVE-2021-37576)

- 在 Linux 核心 5.13.6 之前版本中,drivers/usb/host/max3421-hcd.c 允許鄰近攻擊者藉由在某些情況下移除 MAX-3421 USB 設備來造成拒絕服務 (釋放後使用和損壞)。(CVE-2021-38204)

- 在 Linux 核心 5.13.3 之前版本中,drivers/net/ethernet/xilinx/xilinx_emaclite.c 會列印核心指標 (即真正的 IOMEM 指標),這讓攻擊者更容易破解 ASLR 保護機制。(CVE-2021-38205)

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。
