CVE-2021-3181 (GCVE-0-2021-3181)
Vulnerability from nvd – Published: 2021-01-19 14:30 – Updated: 2024-08-03 16:45
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2020-28896 (GCVE-0-2020-28896)
Vulnerability from nvd – Published: 2020-11-23 18:52 – Updated: 2024-08-04 16:41
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2021-3181 (GCVE-0-2021-3181)
Vulnerability from cvelistv5 – Published: 2021-01-19 14:30 – Updated: 2024-08-03 16:45
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2020-28896 (GCVE-0-2020-28896)
Vulnerability from cvelistv5 – Published: 2020-11-23 18:52 – Updated: 2024-08-04 16:41
VLAI?
Summary
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.
Severity ?
No CVSS data available.
