Description :
This is GNU Bash. Bash is the GNU Project's Bourne Again SHell,
a complete implementation of the POSIX.2 shell spec, but also
with interactive command line editing, job control on architectures
that support it, csh-like features such as history substitution and
brace expansion, and a slew of other features.

я использую pkg(8) и нет /usr/ports. Означает ли это, что сопровождающий не обновил пакет, но список уязвимостей безопасности уже актуален?
похоже, что обновление вышло)

Мне пришлось обновить bash вручную из портов.
Сначала я убедился, что порты обновлены:
portsnap fetch update
Затем я обновил pkg:
cd /usr/ports/ports-mgmt/pkg
make BATCH=yes build
make BATCH=yes deinstall
make BATCH=yes reinstall
Затем я обновил bash:
cd /usr/ports/shells/bash
make BATCH=yes build
make BATCH=yes deinstall
make BATCH=yes reinstall
Моя версия bash теперь актуальна:
