  • Ticket #1602 – Description

    v1 v2  
     1Many methods in the GDAL and OGR, which are also defined in the C-API, do not check if the supplied parameter is valid. Invalid parameter values, notably NULLs given where a string or a handle is expected, lead to a segfault. Since the C-API is open to many scripting languages through the SWIG, and given the way scripting languages are used, it is a common case that invalid values end up to the GDAL and OGR core. Some checks have been introduced to the SWIG interface (for example in ogr.i in OGRLayerShadow *CreateLayer?) but it is probably better to implement all these checks in the C-API. Following is a (not necessarily a comprehensive) list of classes and methods which have this defect:
