[New-bugs-announce] [issue43033] Incorrect handling of PyObject_SetAttrString() in the _zoneinfo module

[Zackery Spytz]

New submission from Zackery Spytz <zspytz at gmail.com>:

There is a PyObject_SetAttrString() call in zoneinfo_init_subclass() which
is not checked for failure.  This could lead to serious bugs if an
exception occurs in PyObject_SetAttrString().
