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 the user can read it through their favorite mail client.

Security Fix(es):

  • fetchmail: DoS or information disclosure when logging long messages (CVE-2021-36386)

  • fetchmail: STARTTLS session encryption bypassing (CVE-2021-39272)
