Samsung Galaxy S2 and Galaxy S3 phones contain a flaw in the Near Field Communication (NFC) functionality. When a malicious user's phone is within close proximity, almost touching the victim's phone, a crafted application can push a second malicious application to the other device. While this functionality is designed to share images, the Galaxy phones will take executables as well. Once the malicious application is pushed, it will be executed immediately without user interaction. This will grant the attacker user level privileges.
