- Date Reported:
- 30 Jun 2020
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 962897.
In Mitre's CVE dictionary: CVE-2020-14093, CVE-2020-14954.
- More information:
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 TLSresponse, 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 1.5.23-3+deb8u2.
We recommend that you upgrade your mutt packages.
