CVE-ID : CVE-2021-3181
Package : mutt
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-1476
The package mutt before version 2.0.5-1 is vulnerable to denial of
service.
Upgrade to 2.0.5-1.
The problem has been fixed upstream in version 2.0.5.
None.
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.
A malicious user could send a malformed email that would crash the
application.
