QID 670941: EulerOS Security Update for mutt (EulerOS-SA-2021-2224)

Mutt is a small but very powerful text-based MIME mail client.Mutt is highly configurable, and is well suited to the mail power user with advanced features like key bindings, keyboard macros, mail threading,regular expression searches and a powerful pattern matching language for selecting groups of messages. 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)
