ALSA-2021:4181 — Moderate: mutt security, bug fix, and enhancement update

Affected: AlmaLinux:8: mutt

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)

fkie_cve-2021-3181

rfc822.c in Mutt through 2.0.4 allows remote attackers to cause a denial of service (mailbox unavailability) by sending email messages with sequences of semicolon characters in RFC822 address fields (aka terminators of empty groups). A small email message from the attacker can cause large memory consumption, and the victim may then be unable to see email messages from other persons.
