Alpine: multiple pyc packages: security update to 3.12.8-r1

high Tenable Cloud Security Plugin ID 424419

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2024-12254)
