RHEL 8 : fetchmail (RHSA-2022:1964)

medium Nessus Plugin ID 161006

Synopsis

The remote Red Hat host is missing one or more security updates for fetchmail.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:1964 advisory.

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)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Additional Changes:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.6 Release Notes linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL fetchmail package based on the guidance in RHSA-2022:1964.
