Arch Linux Security Advisory ASA-202101-43 ========================================== Severity: Low Date : 2021-01-29 CVE-ID : CVE-2021-3181 Package : mutt Type : denial of service Remote : Yes Link : https://security.archlinux.org/AVG-1476 Summary ======= The package mutt before version 2.0.5-1 is vulnerable to denial of service. Resolution ========== Upgrade to 2.0.5-1. # pacman -Syu "mutt>=2.0.5-1" The problem has been fixed upstream in version 2.0.5. Workaround ========== None. Description =========== 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. Impact ====== A malicious user could send a malformed email that would crash the application.
