CVE-2015-1474 is a multiple integer-overflow vulnerability in Android's GraphicBuffer::unflatten function. Android versions through 5.0 improperly handle inputs containing a large number of file descriptors or integer values, resulting in memory corruption. Successful exploitation can allow an attacker to gain privileges or cause a denial of service.

This repository contains a proof-of-concept (POC) exploit for CVE-2015-1474, a vulnerability in the Android SurfaceFlinger service. The main code file, screencap.cpp, is a modified version of the Android screencap utility. It crafts a malicious parcel that, when sent to the SurfaceFlinger service, triggers a crash due to improper deserialization. The exploit demonstrates the vulnerability by causing a denial of service (crash) in SurfaceFlinger, and may be used as a basis for further privilege escalation research. The repository includes build scripts (Android.mk), a README with build and usage instructions, and the main exploit code. The exploit must be compiled within the Android source tree, and requires a minor source modification to the Android framework to expose a necessary method. No network endpoints are involved; the attack vector is local, requiring code execution on the target device.
