Package        : mutt
Version        : 1.5.23-3+deb8u3
CVE ID         : CVE-2020-14093 CVE-2020-14954
Debian Bug     : 


Two vulnerabilities have been discovered in mutt, a console email client.

CVE-2020-14093

    Mutt allowed an IMAP fcc/postpone man-in-the-middle attack via a
    PREAUTH response.

CVE-2020-14954

    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
1.5.23-3+deb8u3.

We recommend that you upgrade your mutt packages.
