今年 10 月份的时候,Android 安全公告用 CVE-2024-40676 的编号公布了一个很奇怪的 patch
AccountManagerService checkKeyIntent() 负责检查 account authenticator 传回的 intent,确保它安全再传回给 caller,防止 launch anywhere 漏洞。这个补丁看起来很暴力也很奇怪,直接 ban 了所有带有 content URI 的 intent,似乎完全不考虑兼容性。是什么样的漏洞才要上如此暴力的修复方法?
注:如下全是我的猜测,由于联系不到漏洞作者本人,无法确认这是否就是原本的问题。

This is a bypass of the initial patch of CVE-2024-0044, a High severity vulnerability in the Android framework that allows attackers with adb access to execute arbitrary code under the UID of arbitrary app.

Magisk App before Canary version 27007 contains a vulnerability CVE-2024-48336, which allows a local untrusted app with no additional privileges to silently execute arbitrary code in the Magisk app and escalate privileges to root via a crafted package without user interaction.

之前一直在看的每月补丁分析的博客 https://wrlus.com/ 看起来是不再更新了,想了想反正自己每个月也要去追着看,干脆写一下分析得了,方便自己后面找。

本人很菜,分析的大部分都是 Java 层漏洞,大佬别骂我 QAQ

最初发表在我的 telegram 频道。每月补丁都会在此文中更新。
