Hi.

/var/log/apache is world-readable, so users can e.g. check whether
certain operation triggered an error.  And given that the error strings
are pretty standardized, they can guess what string has been added to
the logfile, judging by the number of bytes that was appended to the
log.

As this is not very obvious to the system administrator, and as there is
no use of /var/log/apache directory being readable and searchable while
the files in it are not, apart from the information disclosure described
above, I think it should be chmod-ed 750, just as the logs in it are
chmod 640.

Thanks.
Jan.

There is no point in such operation. If a user have a local account
it also has at least a few other thousands options to make a DoS on apache.
