Description Pedro Sampaio 2020-02-05 14:51:59 UTC 
An issue was discovered in Squid before 4.10. It allows a crafted FTP server to trigger disclosure of sensitive information from heap memory, such as information associated with other users' sessions or non-Squid processes.

Created squid tracking bugs for this issue:

Affects: fedora-all [bug 1798535]
Comment 2 Stefan Cornelius 2020-02-13 10:26:05 UTC 
Mitigation:

As a workaround, it is possible to disable support for FTP. In order to do so, remove the following line from your squid configuration file:
acl Safe_ports 21

Then add the following lines to your squid configuration file:
acl FTP proto FTP
http_access deny FTP
