CVE-2024-12254

Starting in Python 3.12.0, the asyncio._SelectorSocketTransport.writelines()
 method would not "pause" writing and signal to the Protocol to drain 
the buffer to the wire once the write buffer reached the "high-water 
mark". Because of this, Protocols would not periodically drain the write
 buffer potentially leading to memory exhaustion.





This
 vulnerability likely impacts a small number of users, you must be using
 Python 3.12.0 or later, on macOS or Linux, using the asyncio module 
with protocols, and using .writelines() method which had new 
zero-copy-on-write behavior in Python 3.12.0 and later. If not all of 
these factors are true then your usage of Python is unaffected.

CWE-400 Uncontrolled Resource Consumption

The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

CWE-770 Allocation of Resources Without Limits or Throttling

The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor.
