Description Jan Lieskovsky 2008-07-11 10:44:48 UTC
Description of problem:

Justin Ferguson has reported the following python issue:

The unicode_resize() function acts essentially as a wrapper to
realloc(), it accomplishes this via the PyMem_RESIZE() macro which
factors the size with the size of the type, in this case it multiplies
by two as Py_UNICODE is typedef'd to a wchar_t. When resizing large
strings, this results in an incorrect allocation that in turn leads to
buffer overflow.
