本 Pixel 更新公告详细介绍了会影响受支持的 Pixel 设备（以下简称 Google 设备）的安全漏洞和功能改进。对于 Google 设备，如果安全补丁程序级别是 2019-10-05 或更新，则意味着已解决本公告以及 2019 年 10 月的 Android 安全公告中所述的所有问题。如需了解如何查看设备的安全补丁级别，请参阅查看并更新 Android 版本。
所有受支持的 Google 设备都将会收到 2019-10-05 补丁级别的更新。建议所有用户都在自己的设备上接受这些更新。
通告
- Pixel 1 和 Pixel 2 设备将在 10 月更新期间收到 CVE-2019-2215 补丁程序。Pixel 3 和 Pixel 3a 设备不会受到此问题的影响。
- 除了 2019 年 10 月的 Android 安全公告中所述的安全漏洞外，Google 设备中还包含针对下述安全漏洞的补丁程序。在适用情况下，合作伙伴在至少一个月前就已收到关于这些问题的通知，并可以选择将针对这些问题的补丁程序纳入到其设备更新中。
安全补丁
漏洞按照其影响的组件进行分类，内容包括问题描述和一个表，该表中包含 CVE、相关参考编号、漏洞类型、严重程度和已更新的 Android 开源项目 (AOSP) 版本（若有）。如果有解决相应问题的公开更改记录（例如 AOSP 代码更改列表），我们会将 bug ID 链接到该记录。如果某个 bug 有多条相关的代码更改记录，我们还会通过 bug ID 后面的数字链接到更多参考内容。

常见问题和解答
这一部分解答了用户在阅读本公告后可能会提出的常见问题。
1. 如何确定我的设备是否已通过更新解决这些问题？
如果安全补丁级别是 2019-10-05 或更新，则意味着已解决 2019-10-05 以及之前的所有安全补丁级别涵盖的所有问题。若要了解如何查看设备的安全补丁级别，请参阅 Google 设备更新时间表中的说明。
2. “类型”列中的条目表示什么意思？
在漏洞详情表内，“类型”列中的条目是安全漏洞的分类。
| 缩写词 |
定义 |
| RCE |
远程代码执行 |
| EoP |
提权 |
| ID |
信息披露 |
| DoS |
拒绝服务攻击 |
| N/A |
没有分类 |
3. “参考编号”列中的条目表示什么意思？
在漏洞详情表内，“参考编号”列中的条目可能包含用于标识参考编号值所属组织的前缀。
| 前缀 |
参考编号 |
| A- |
Android bug ID |
| QC- |
Qualcomm 参考编号 |
| M- |
MediaTek 参考编号 |
| N- |
NVIDIA 参考编号 |
| B- |
Broadcom 参考编号 |
4. 在“参考编号”列中，Android bug ID 旁边的 * 表示什么意思？
如果问题尚未公开发布，则在“参考编号”列中，相应 Android bug ID 旁边会显示 *。Google Developers 网站上针对 Pixel 设备的最新二进制驱动程序中通常包含用于解决相应问题的更新。
5. 为什么要将安全漏洞拆分到本公告和 Android 安全公告中？
若要声明 Android 设备的最新安全补丁级别，必须修复 Android 安全公告中记录的安全漏洞。但在声明安全补丁级别时，并不是必须要修复其他安全漏洞（如本公告中记录的漏洞）。
