透過集合功能整理內容
你可以依據偏好儲存及分類內容。
發布日期:2021 年 12 月 6 日
Android Automotive OS (AAOS) 更新公告列舉對 Android Automotive OS 平台造成影響的安全漏洞,並說明相關細節。完整的 AAOS 更新除了提供 2021 年 12 月 Android 安全性公告中的安全性修補程式等級 (2021-12-05 之後),也解決了這個公告列出的所有問題。
我們建議所有客戶接受這些裝置更新。
在這些問題中,最嚴重的就是平台應用程式元件中嚴重程度「高」的安全漏洞。本機惡意應用程式可利用這類漏洞規避使用者互動要求,直接取得其他權限。
嚴重程度評定標準是假設平台與服務的因應防護措施基於開發作業需求而關閉,或是遭到有心人士成功規避,然後推算當有人惡意運用漏洞時,使用者裝置會受到多大影響,並據此評定漏洞的嚴重程度。

除了修補 2021 年 12 月 Android 安全性公告列出的安全漏洞外,2021 年 12 月 Android Automotive OS 更新公告也專為下文列出的 AAOS 安全漏洞提供修補程式。
2021-12-01 安全性修補程式等級安全漏洞詳情
下列各節針對 2021-12-01 安全性修補程式等級適用的各項安全性漏洞提供了詳細資訊。我們依照資安問題本身所影響的元件將各項漏洞分門別類,並在下方表格中列出問題的相關資訊,包括 CVE ID、相關參考資料、漏洞類型、嚴重程度。在適用情況下,我們也會提供更新的 Android 開放原始碼計畫版本。假如相關錯誤有公開變更,該錯誤 ID 會連結到相對應的變更 (例如 Android 開放原始碼計畫變更清單)。如果單一錯誤有多項相關變更,其他參考資料可透過該錯誤 ID 後面的編號連結開啟。搭載 Android 10 以上版本的裝置可能會收到安全性更新和 Google Play 系統更新。
本節中最嚴重的安全漏洞,可能會讓本機惡意應用程式規避使用者互動要求,直接取得其他權限。

常見問題與解答
如果閱讀這篇公告後有任何疑問,可參考本節的常見問答。
1. 如何判斷我的裝置軟體版本是否更新並修正問題?
請參閱 Google 裝置更新時間表中的操作說明,瞭解如何查看裝置的安全性修補程式等級。
- 如果是 2021-12-01 之後的安全性修補程式等級,代表 2021-12-01 安全性修補程式等級涵蓋的所有問題都已解決。
提供這些更新的裝置製造商應將修補程式字串等級設定為:
- [ro.build.version.security_patch]:[2021-12-01]
如果是搭載 Android 10 以上版本的裝置,Google Play 系統更新的日期字串應與 2021-12-01 安全性修補程式等級相同。如要進一步瞭解如何安裝安全性更新,請參閱這個頁面。
2. 「類型」欄中的項目代表什麼意義?
在安全漏洞詳情表中,「類型」欄中的項目代表安全漏洞類別。
縮寫 |
定義 |
RCE |
遠端程式碼執行 |
EoP |
權限提升 |
ID |
資訊外洩 |
DoS |
阻斷攻擊 |
不適用 |
未分類 |
3. 「參考資料」欄中的項目代表什麼意義?
在安全漏洞詳情表格中,「參考資料」欄的項目可能包含前置字串,表示該參考資料值所屬的機構。
前置字串 |
參考資料 |
A- |
Android 錯誤 ID |
QC- |
Qualcomm 參考編號 |
M- |
MediaTek 參考編號 |
N- |
NVIDIA 參考編號 |
B- |
Broadcom 參考編號 |
U- |
UNISOC 參考編號 |
4. 「參考資料」欄中,Android 錯誤 ID 旁的星號 (*) 代表什麼?
在對應的參考資料 ID 旁邊標上星號 (*) 代表該問題並未公開,用於解決問題的更新通常會直接整合在 Pixel 裝置的最新二進位驅動程式。您可以前往 Google Developers 網站下載這些驅動程式。
5. 為什麼安全漏洞會分別刊載在這份安全性公告和裝置/合作夥伴安全性公告 (例如 Pixel 公告)?
刊載在此安全性公告的安全漏洞,都是宣告 Android 裝置最新安全性修補程式等級時必須修正的問題。裝置/合作夥伴安全性公告刊載的其他安全漏洞,對於宣告安全性修補程式等級並非必要。Android 裝置和晶片組製造商也可能會針對該公司的產品發布安全漏洞詳細資料,例如:Google、Huawei、LGE、Motorola、Nokia 或 Samsung。

How do I determine if my device is updated to address these\nissues?**\n\nTo learn how to check a device's security patch level, read the instructions on the\n[Google device\nupdate schedule](https://support.google.com/android/answer/7680439).\n\n- Security patch levels of 2021-12-01 or later address all issues associated with the 2021-12-01 security patch level.\n\nDevice manufacturers that include these updates should set the patch string level to:\n\n- \\[ro.build.version.security_patch\\]:\\[2021-12-01\\]\n\nFor some devices on Android 10 or later, the Google Play system update\nhas a date string that matches the 2021-12-01\nsecurity patch level.\nSee [this\npage](https://support.google.com/android/answer/7680439) for more details on how to install\nsecurity updates.\n\n\n**2. What do the entries in the *Type* column mean?**\n\nEntries in the *Type* column of the vulnerability details table\nreference the classification of the security vulnerability.\n\n| Abbreviation | Definition |\n|--------------|------------------------------|\n| RCE | Remote code execution |\n| EoP | Elevation of privilege |\n| ID | Information disclosure |\n| DoS | Denial of service |\n| N/A | Classification not available |\n\n\n**3. What do the entries in the *References* column mean?**\n\nEntries under the *References* column of the vulnerability details\ntable might contain a prefix identifying the organization to which the reference\nvalue belongs.\n\n| Prefix | Reference |\n|--------|---------------------------|\n| A- | Android bug ID |\n| QC- | Qualcomm reference number |\n| M- | MediaTek reference number |\n| N- | NVIDIA reference number |\n| B- | Broadcom reference number |\n| U- | UNISOC reference number |\n\n\n**4. What does an \\* next to the Android bug ID in the *References*\ncolumn mean?**\n\nIssues that aren't publicly available have an \\* next to the corresponding\nreference ID. The update for that issue is generally contained in the latest\nbinary drivers for Pixel devices available from the\n[Google Developer site](https://developers.google.com/android/drivers).\n\n**5. Why are security vulnerabilities split between this bulletin and\ndevice or partner security bulletins, such as the\nPixel bulletin?**\n\nSecurity vulnerabilities that are documented in this security bulletin are\nrequired to declare the latest security patch level on Android\ndevices. Additional security vulnerabilities that are documented in the\ndevice or partner security bulletins aren't required for\ndeclaring a security patch level. Android device and chipset manufacturers\ncan also publish security vulnerability details specific to their products,\nsuch as\n[Google](/security/bulletin/pixel),\n[Huawei](https://consumer.huawei.com/en/support/bulletin/),\n[LGE](https://lgsecurity.lge.com/security_updates_mobile.html),\n[Motorola](https://motorola-global-portal.custhelp.com/app/software-security-page/g_id/6806),\n[Nokia](https://www.nokia.com/phones/en_int/security-updates), or\n[Samsung](https://security.samsungmobile.com/securityUpdate.smsb).\n\nVersions\n--------\n\n| Version | Date | Notes |\n|---------|------------------|-------------------|\n| 1.0 | December 6, 2021 | Bulletin Released |"]]
