An update for mutt is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1079 Final 1.0 1.0 2021-03-05 Initial 2021-03-05 2021-03-05 openEuler SA Tool V1.0 2021-03-05 mutt security update An update for mutt is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1. Mutt is a small but very powerful text-based mail client for Unix operating systems. Security Fix(es): 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.(CVE-2021-3181) An update for mutt is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of medium.
