New submission from Alex CHEN:
Hi,
Our tool reported a position that doesn't check for returned value (from a
function that might returns null). might need a look that is there any problem
or I am missing something.
in function PyUnknownEncodingHandler of file pyexpat.c,
if (namespace_separator != NULL) {
self->itself = XML_ParserCreateNS(encoding, *namespace_separator);
}
else {
self->itself = XML_ParserCreate(encoding); // could
XML_ParserCreate returns null in this point?
}
.....
XML_SetHashSalt(self->itself, // if it does
return null, null pointer will passed into XML_SetHashSalt and will be
dereferenced.
(unsigned long)_Py_HashSecret.prefix);
#endif
