Package: spamassassin
Version: 3.2.0-2
Severity: important

sa-update being started from cron.daily is probably a DoS attack against
Spamassassin update servers.

Although it is not the default configuration, many users will activate
automatic rule updates via sa-update with the mechanism provided in
/etc/cron.daily/spamassassin in the latest Debian package, downloading
new rules from Spamassassin update servers (starting from
updates.spamassassin.org).

cron.daily is executed at 06:25 local time on a standard Debian system,
so all installations within the same timezone will hit the update
servers at about the 25th minute of an hour, deviating only by the
execution time of other scripts in cron.daily. This might not be
noticeable during Testing, but it will wreak havoc on those servers once
this version of Spamassassin enters a Stable version of Debian.

The current behaviour should be changed so that the time of download of
updates is spread evenly over at least one full hour for all systems in
the same timezone. The time chosen for download could be either random
for each execution, or it could be random but fixed per machine (in
which case the time would be determined once during package
configuration and then saved and reused).
