一、漏洞信息
漏洞编号：CVE-2024-12254
漏洞归属组件：python2
漏洞归属的版本：2.7.18
CVSS V3.0分值：
BaseScore：7.5 High
Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
漏洞简述：
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.
