[SECURITY] [DLA 2268-1] mutt security update

Package        : mutt
Version        : 1.5.23-3+deb8u2
CVE ID         : CVE-2020-14093 CVE-2020-14954
Debian Bug     : 962897

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."

For Debian 8 "Jessie", these problems have been fixed in version

We recommend that you upgrade your mutt packages.
