Methods for performining cross module context-sensitive security analysis
A computer-implemented method for detecting program bugs in source code of a computer program that includes a plurality of source modules, each of the plurality of source modules including at least a set of subroutines, is provided. The method includes performing summary collection on subroutines of the plurality of source modules. Performing the summary collection includes collecting first data pertaining to at least untrusted data in each of the subroutines of the plurality of source modules. The method also includes storing the first data in a set of intermediate files. The method further includes performing interprocedural analysis on the set of intermediate files. The interprocedural analysis is configured to identify at least first untrusted data in a given subroutine of the subroutines of the plurality of source modules and to map a data flow tracking the first untrusted data across at least two of the plurality of source modules.
