Right, the description could have been more descriptive but is caused
by the following: The issue was not yet public at the time of the
upload, nor the CVE, but upstream was fine to Debian first issue an
update and then publish the GHSA. This was the reason that the
changelog entry gives not detail on what is wrong with mail.

We could re-trospectively ask for -3 with a more descriptive changelog
entry and include the CVE, but I would suggest to just unblock what we
have.

Regards,
Salvatore

Would it be better to have the CVE mentioned in the changelog?

Hi Release Team!

Please unblock package fail2ban

fail2ban is affected by CVE-2021-32749, see detailed advisory in
https://github.com/fail2ban/fail2ban/security/advisories/GHSA-m985-3f3v-cwmm,
which is a possible remote code execution vulnerability in the mailing
action mail-whois.

The idea is to have it fixed in the upper suite first, later for
buster a point release update could follow.

unblock fail2ban/0.11.2-2

Regards,
Salvatore
