Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the SelectorSocketTransport.writelines method not draining its buffers, when Protocols are in use. An attacker can cause this behavior which eventually exhausts available memor...

PSF-2024-14

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...

CVE-2024-12254

Summary (CVE-2024-12254): In Python 3.12.0+ the asyncio._SelectorSocketTransport.writelines() path may fail to pause and drain the write buffer at the high-water mark, causing unbounded memory buffering and potential exhaustion. Affected: Python 3.12.x with asyncio protocols using writelines(); r...
