    Two vulnerabilities have been discovered in mutt, a console email client. CVE-2020-14093
    Package        : mutt
    Version        : 1.5.23-3+deb8u3

    Debian Bug     : 
    Two vulnerabilities have been discovered in mutt, a console email client.
        Mutt allowed an IMAP fcc/postpone man-in-the-middle attack via a
        PREAUTH response.
        Mutt had a STARTTLS buffering issue that affected IMAP, SMTP, and
        POP3. When a server had sent a "begin TLS" response, the client read
        additional data (e.g., from a man-in-the-middle attacker) and
        evaluated it in a TLS context, aka "response injection."
    In Debian jessie, the mutt source package builds two variants of mutt:
    mutt and mutt-patched.
    The previous package version (1.5.23-3+deb8u2, DLA-2268-1) provided fixes
    for the issues referenced above, but they were only applied for the
    mutt-patched package build, not for the (vanilla) mutt package build.
    For Debian 8 "Jessie", this problem has been fixed in version
    We recommend that you upgrade your mutt packages.
