New submission from Alexey Izbyshev <izbys...@ispras.ru>:
The return value of PyTuple_GetSlice() at https://github.com/python/cpython/blob/48ce4897f8f8d91d948ecd1241ffab002df2be9e/Objects/typeobject.c#L2297 is not checked for NULL and then dereferenced. Reported by Svace static analyzer. Currently, PyTuple_GetSlice() for a zero-length slice can fail only if it's the first zero-length tuple ever created. If there is an invariant that at least one zero-length tuple exists on any type_init() call, the check may be replaced with an assert. ---------- components: Interpreter Core messages: 323951 nosy: berker.peksag, izbyshev, pitrou, serhiy.storchaka priority: normal severity: normal status: open title: Objects/typeobject.c: Missing NULL check in type_init() type: behavior versions: Python 2.7, Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34477> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
