Raw Blame History

5.3.0

Deprecated APIs

  • The UnknownDefaultLocation, UnknownExprLocation, and UnknownStmtLocation classes have been deprecated. Use UnknownLocation instead.

New Features

  • Added a isFinalValueOfParameter predicate to DataFlow::Node which holds when a dataflow node represents the final value of an output parameter of a function.

Minor Analysis Improvements

  • The FunctionWithWrappers library (semmle.code.cpp.security.FunctionWithWrappers) no longer considers calls through function pointers as wrapper functions.
  • The analysis of C/C++ code targeting 64-bit Arm platforms has been improved. This includes support for the Arm-specific builtin functions, support for the arm_neon.h header and Neon vector types, and support for the fp8 scalar type. The arm_sve.h header and scalable vectors are only partially supported at this point.
  • Added support for __fp16 _Complex and __bf16 _Complex types
  • Added sql-injection sink models for the Oracle Call Interface (OCI) database library functions OCIStmtPrepare and OCIStmtPrepare2.
