Ubuntu 16.04 LTS / 18.04 LTS:Linux 核心弱點 (USN-5209-1)

high Nessus Plugin ID 156484

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-5209-1 公告中所提及的多個弱點影響。

- 在 5.14.12 更舊版本的 Linux 核心中,kernel/bpf/stackmap.c 中的 prealloc_elems_and_freelist 允許無權限使用者觸發 eBPF 乘法整數溢出,進而導致超出邊界寫入問題。(CVE-2021-41864)

- 在 Linux 核心中發現一個缺陷。NFC 堆疊中的釋放後使用弱點可能會對機密性、完整性和系統可用性造成威脅。(CVE-2021-3760)

- 在 Linux 核心中發現一個缺陷。損壞的計時器樹導致 lib/timerqueue.c 中的 timerqueue_add 函數中缺少工作喚醒。此缺陷允許具有特殊使用者權限的本機攻擊者造成拒絕服務的狀況,進而在執行 OSP 時減慢並最終停止系統。
(CVE-2021-20317)

- 在使用者使用 OverlayFS 以特定方式重新命名的方式中,發現存取 Linux 核心 OverlayFS 子系統中檔案物件的爭用情形。本機使用者可能會利用此缺陷造成系統當機。
(CVE-2021-20321)

- 在 5.14.15 版之前的 Linux 核心中發現一個問題。drivers/isdn/capi/kcapi.c 的 detach_capi_ctr 函式中存在一個 array-index-out-of-bounds 缺陷。(CVE-2021-43389)

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作出判斷。
