Multiple integer overflows in Python 2.5.2 allow context-dependent
attackers to have an unknown impact via a large integer value in the
tabsize argument to the expandtabs method, as implemented by (1) the
string_expandtabs function in Objects/stringobject.c and (2) the
unicode_expandtabs function in Objects/unicodeobject.c.  NOTE: this
vulnerability reportedly exists because of an incomplete fix for
CVE-2008-2315.
