Summary
Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that $ssl_force_tls was processed if an IMAP server's initial server response was invalid. The connection was not properly closed, and the code could continue attempting to authenticate. This could result in authentication credentials being exposed on an unencrypted connection, or to a machine-in-the-middle.

Summary
Red Hat Security Advisory: mutt security, bug fix, and enhancement update
Notes
Topic
An update for mutt is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Mutt is a low resource, highly configurable, text-based MIME e-mail client. Mutt supports most e-mail storing formats, such as mbox and Maildir, as well as most protocols, including POP3 and IMAP.
The following packages have been upgraded to a later upstream version: mutt (2.0.7). (BZ#1912614)
Security Fix(es):
* mutt: Incorrect handling of invalid initial IMAP responses could lead to an authentication attempt over unencrypted connection (CVE-2020-28896)
* mutt: Memory leak when parsing rfc822 group addresses (CVE-2021-3181)
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 8.5 Release Notes linked from the References section.

Summary
Red Hat Security Advisory: mutt security, bug fix, and enhancement update
Notes
Topic
An update for mutt is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Mutt is a low resource, highly configurable, text-based MIME e-mail client. Mutt supports most e-mail storing formats, such as mbox and Maildir, as well as most protocols, including POP3 and IMAP.
The following packages have been upgraded to a later upstream version: mutt (2.0.7). (BZ#1912614)
Security Fix(es):
* mutt: Incorrect handling of invalid initial IMAP responses could lead to an authentication attempt over unencrypted connection (CVE-2020-28896)
* mutt: Memory leak when parsing rfc822 group addresses (CVE-2021-3181)
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.

Summary
Red Hat Security Advisory: mutt security, bug fix, and enhancement update
Notes
Topic
An update for mutt is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Mutt is a low resource, highly configurable, text-based MIME e-mail client. Mutt supports most e-mail storing formats, such as mbox and Maildir, as well as most protocols, including POP3 and IMAP.
The following packages have been upgraded to a later upstream version: mutt (2.0.7). (BZ#1912614)
Security Fix(es):

Summary
Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that $ssl_force_tls was processed if an IMAP server's initial server response was invalid. The connection was not properly closed, and the code could continue attempting to authenticate. This could result in authentication credentials being exposed on an unencrypted connection, or to a machine-in-the-middle.
