Synopsis

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

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2021:4181 advisory.

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)
