+=======================================
+
+Checks C++ copy and move assignment operators for self assignment.

+The `clang-analyzer-cplusplus.SelfAssignment` check is an alias, please see
+`Clang Static Analyzer Available Checkers
+<https://clang.llvm.org/docs/analyzer/checkers.html#cplusplus-stringchecker>`_
+for more information.

 clang-analyzer-security.PutenvStackArray
 ========================================
 
-Finds calls to the function 'putenv' which pass a pointer to an automatic
-(stack-allocated) array as the argument.
+Finds calls to the putenv function which pass a pointer to a stack-allocated
+(automatic) array as the argument. Function putenv does not copy the passed
+string, only a pointer to the data is stored and this data can be read even by
+other threads. Content of a stack-allocated array is likely to be overwritten
+after exiting from the function.

 clang-analyzer-security.SetgidSetuidOrder
 =========================================
 
-Warn on possible reversed order of 'setgid(getgid()))' and 'setuid(getuid())'
-(CERT: POS36-C).
+The checker checks for sequences of ``setuid(getuid())`` and ``setgid(getgid())``
+calls (in this order). If such a sequence is found and there is no other
+privilege-changing function call (``seteuid``, ``setreuid``, ``setresuid`` and
+the GID versions of these) in between, a warning is generated. The checker finds
+only exactly ``setuid(getuid())`` calls (and the GID versions), not for example
+if the result of ``getuid()`` is stored in a variable.
