How to fix?

Upgrade SLES:15.4 libpython3_10-1_0 to version 3.10.20-150400.4.115.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libpython3_10-1_0 package and not the libpython3_10-1_0 package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

The ftpcp() function in Lib/ftplib.py was not updated when CVE-2021-4189 was fixed. While makepasv() was patched to replace server-supplied PASV host addresses with the actual peer address (getpeername()[0]), ftpcp() still calls parse227() directly and passes the raw attacker-controllable IP address and port to target.sendport(). This patch is related to CVE-2021-4189.
