Various vulnerabilities of Android have been reported, threatening users. Among them, vulnerabilities from Android Media Framework are known to be highly dangerous because they allow malicious users to manipulate media data inputs. This paper proposes an analysis tool for triaging vulnerabilities of Android Media Framework in order to identify urgent patches. The proposed tool identifies the severity of a vulnerability by figuring out the exploitability. We conduct forward and backward static analysis to determine the relationship between vulnerable C/C code and JNI (thus Java applications and user inputs), and we demonstrate the feasibility of our approach by experimenting with vulnerabilities in Android Media Framework. |
