Claim Text:
1. A method for detecting a security vulnerability for an animation source file implemented by a computer communicatively coupled to a network wherein the computer includes one or more processors, a memory and a communication unit, the computer by a transmission unit, the method comprising: receiving by the communication unit the animation source file; decompiling by the processor the animation source file, and acquiring a program structure and a syntactic model of the animation source file; converting the program structure and the syntactic model into an abstract syntax tree (AST); constructing symbol tables and function summaries for functions of the animation source file based on the AST, wherein each function of the animation source file corresponds to one symbol table and one function symbol; and performing a taint backtracking on the symbol tables and the function summaries, and detecting whether the animation source file has the security vulnerability according to a pre-registered vulnerability rule.
