Breaking Changes

The predicates in the MustFlow::Configuration class used by the MustFlow library (semmle.code.cpp.ir.dataflow.MustFlow) have changed to be defined directly in terms of the C++ IR instead of IR dataflow nodes.

Deprecated APIs

  • Deprecated semmle.code.cpp.ir.dataflow.DefaultTaintTracking. Use semmle.code.cpp.ir.dataflow.TaintTracking.
  • Deprecated semmle.code.cpp.security.TaintTrackingImpl. Use semmle.code.cpp.ir.dataflow.TaintTracking.
  • Deprecated semmle.code.cpp.valuenumbering.GlobalValueNumberingImpl. Use semmle.code.cpp.valuenumbering.GlobalValueNumbering, which exposes the same API.

Minor Analysis Improvements

  • The ArgvSource flow source now uses the second parameter of main as its source instead of the uses of this parameter.
  • The ArgvSource flow source has been generalized to handle cases where the argument vector of main is not named argv.
  • The getaddrinfo function is now recognized as a flow source.
  • The secure_getenv and _wgetenv functions are now recognized as local flow sources.
  • The scanf and fscanf functions and their variants are now recognized as flow sources.
  • Deleted the deprecated getName and getShortName predicates from the Folder class.
