fedora
Calendar Grey September 24, 2021
Dist Fedora Esm H88
Upgrade the fetchmail package to version 6.4.22 to mitigate the STARTTLS encryption vulnerability on Fedora environments.
Update to fetchmail-6.4.22 (CVE-2021-39272)

Summary

Fetchmail is a remote mail retrieval and forwarding utility intended

for use over on-demand TCP/IP links, like SLIP or PPP connections.

Fetchmail supports every remote-mail protocol currently in use on the

Internet (POP2, POP3, RPOP, APOP, KPOP, all IMAPs, ESMTP ETRN, IPv6,

and IPSEC) for retrieval. Then Fetchmail forwards the mail through

SMTP so you can read it through your favorite mail client.

Install fetchmail if you need to retrieve mail over SLIP or PPP

connections.
