CVSS v3.1 |
| Stack-based buffer overflow in the browse_get_namespace function in imap/browse.c of Mutt 1.4.2.1 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via long namespaces received from the IMAP server. |
| The write_one_header function in mutt 1.5.23 does not properly handle newline characters at the beginning of a header, which allows remote attackers to cause a denial of service (crash) via a header with an empty body, which triggers a heap-based buffer overflow in the mutt_substrdup function. |
| Buffer overflow in copy.c in Mutt before 1.5.23 allows remote attackers to cause a denial of service (crash) via a crafted RFC2047 header line, related to address expansion. |
| Mutt does not verify that the smtps server hostname matches the domain name of the subject of an X.509 certificate, which allows man-in-the-middle attackers to spoof an SSL SMTP server via an arbitrary certificate, a different vulnerability than CVE-2009-3766. |
| rfc822.c in Mutt through 2.0.4 allows remote attackers to cause a denial of service (mailbox unavailability) by sending email messages with sequences of semicolon characters in RFC822 address fields (aka terminators of empty groups). A small email message from the attacker can cause large memory consumption, and the victim may then be unable to see email messages from other persons. |
| Mutt 1.11.0 through 2.0.x before 2.0.7 (and NeoMutt 2019-10-25 through 2021-05-04) has a $imap_qresync issue in which imap/util.c has an out-of-bounds read in situations where an IMAP sequence set ends with a comma. NOTE: the $imap_qresync setting for QRESYNC is not enabled by default. |
| Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that $ssl_force_tls was processed if an IMAP server's initial server response was invalid. The connection was not properly closed, and the code could continue attempting to authenticate. This could result in authentication credentials being exposed on an unencrypted connection, or to a machine-in-the-middle. |
| Mutt before 1.14.4 and NeoMutt before 2020-06-19 have a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a "begin TLS" response, the client reads additional data (e.g., from a man-in-the-middle attacker) and evaluates it in a TLS context, aka "response injection." |
| Mutt before 1.14.3 proceeds with a connection even if, in response to a GnuTLS certificate prompt, the user rejects an expired intermediate certificate. |
| Mutt before 1.14.3 allows an IMAP fcc/postpone man-in-the-middle attack via a PREAUTH response. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. pop.c does not forbid characters that may have unsafe interaction with message-cache pathnames, as demonstrated by a '/' character. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. They have a buffer overflow via base64 data. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. imap/message.c has a stack-based buffer overflow for a FETCH response with a long RFC822.SIZE field. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. They allow remote IMAP servers to execute arbitrary commands via backquote characters, related to the mailboxes command associated with an automatic subscription. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. pop.c mishandles a zero-length UID. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. imap/util.c mishandles ".." directory traversal in a mailbox name. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. They allow remote IMAP servers to execute arbitrary commands via backquote characters, related to the mailboxes command associated with a manual subscription or unsubscription. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. imap_quote_string in imap/util.c has an integer underflow. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. imap_quote_string in imap/util.c does not leave room for quote characters, leading to a stack-based buffer overflow. |
| An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. imap/command.c mishandles a long IMAP status mailbox literal count size. |
