New submission from Christian Heimes:
The function _PyImport_GetDynLoadFunc() in Python/dynload_shlib.c doesn't check
the return value of fstat()
CID 486250: Other violation (CHECKED_RETURN)At (3): Calling function
"fstat(fileno(fp), &statb)" without checking return value. This library
function may fail and return an error code.
At (4): No check of the return value of "fstat(fileno(fp), &statb)".
93 fstat(fileno(fp), &statb);
Suggested fix:
if (fstat(fileno(fp), &statb) == -1) {
PyErr_SetFromErrnoWithFilename(PyExc_IOError, pathname);
return NULL;
}
}
