Debian LTS Advisory DLA-2529-1 [email protected]
https://www.debian.org/lts/security/ Utkarsh Gupta

Package : mutt
Version : 1.7.2-1+deb9u5
CVE ID : CVE-2021-3181
Debian Bug : 980326
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.
For Debian 9 stretch, this problem has been fixed in version
1.7.2-1+deb9u5.
We recommend that you upgrade your mutt packages.
