openSUSE 安全性更新：Linux 核心 (openSUSE-2016-256)
high Nessus Plugin ID 88927
語系：
概要
遠端 openSUSE 主機缺少安全性更新。說明
openSUSE 13.2 核心已更新，可接收多個安全性和錯誤修正。其也修正了一個會造成 Chromium 沙箱不再運作的迴歸 (bsc#965356)。
已修正下列安全性錯誤：
- CVE-2016-2069：在 Linux 處理分頁結構的方式中發現一個瑕疵。Linux 使未在本機中使用的分頁結構無效時，在主體中，其可與切換至分頁結構有問題之處理程序的其他 CPU 爭用，進而造成本機拒絕服務 (機器當機)。
(bnc#963767)。
- CVE-2016-0723：Linux 核心中 drivers/tty/tty_io.c 的 tty_ioctl 函式有爭用情形，其允許本機使用者在處理 TIOCSETD ioctl 呼叫期間提出 TIOCGETD ioctl 呼叫，進而從核心記憶體取得敏感資訊，或造成拒絕服務 (釋放後使用和系統當機) (bnc#961500)。
下列非安全性錯誤已修正：
- Bluetooth：ath3k：針對 xHCI 控制器的相容性問題提供因應措施 (bnc#907378)。
- 針對加入 user_namespace.flags 欄位的 kABI 修正 (bnc#965308、bnc#965356)。
- userns：新增 knob 以按每使用者命名空間停用 setgroups (bnc#965308、bnc#965356)。
- userns：setgroups 停用時，允許在無權限的情況下設定 gid_maps (bnc#965308、bnc#965356)。
- userns：將 id_map_mutex 重新命名為 userns_state_mutex (bnc#965308、bnc#965356)。
