CVE-2017-13253
HIGHAndroid 8.0 8.1 - Out-of-bounds Write in CryptoPlugin::decrypt
Title source: llmExploitation Summary
EIP tracks 3 public exploits for CVE-2017-13253. PoCs published by Tamir Zahavi-Brunner, tamirzb, codecat007.
AI-analyzed exploit summary This exploit demonstrates a heap overflow vulnerability in the Android media.drm service (CVE-2017-13253) by manipulating memory buffers during a decrypt operation. The PoC triggers the overflow by setting up a source and destination buffer with overlapping regions, leading to potential arbitrary code execution.
Description
In CryptoPlugin::decrypt of CryptoPlugin.cpp, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation. Product: Android. Versions: 8.0, 8.1. Android ID: A-71389378.

This exploit demonstrates a heap overflow vulnerability in the Android media.drm service (CVE-2017-13253) by manipulating memory buffers during a decrypt operation. The PoC triggers the overflow by setting up a source and destination buffer with overlapping regions, leading to potential arbitrary code execution.
This PoC demonstrates a buffer overflow vulnerability (CVE-2017-13253) in Android's DRM services (8.0-8.1 pre-March 2018) by exploiting a heap overflow in the `decrypt` method of the ClearKey DRM plugin. The exploit triggers a segmentation fault by overwriting protected memory, with outcomes varying based on vendor implementation and patch status.
This PoC demonstrates a heap overflow vulnerability in Android's ClearKey DRM module (CVE-2017-13253) by creating overlapping memory regions and triggering a decryption operation that leads to a buffer overflow. The exploit targets the `media.drm` service and manipulates memory allocations to achieve the overflow.
