Mageia 2021-0070: mutt security update

Date 05 Feb 2021

Posted By LinuxSecurity Advisories
It was discovered that Mutt incorrectly handled certain email messages. An attacker could possibly use this issue to cause a denial of service because 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).
