Mutt is a small but very powerful text-based mail client.
A heap-based buffer overflow was discovered in Mutt’s mutt_substrdup function.
A remote attacker could cause a Denial of Service condition.
There is no known workaround at this time.
All Mutt users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mutt-1.5.23-r5"
OS | Version | Architecture | Package | Version | Filename |
