Doc Text:	A flaw was found in SciPy, where it is vulnerable to a denial of service caused by a memory leak flaw in the Py_FindObjects() function due to a new reference not being decreased. This flaw allows a local attacker to send a specially crafted request, forcing the application to leak memory and perform a denial of service attack.	Story Points:	---
