CVE-2026-8328  (opens in a new tab)

How to fix?

Upgrade SLES:15.7 python-base to version 2.7.18-150000.123.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-base package and not the python-base package as distributed by SLES. See How to fix? for SLES:15.7 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.
