Hi,

 

a routine scan revealed a possible DOS attack vector: sending an invalid POST HTTP request with a negative Content-Length field crashes our elog instance, leading to service unavailability.

 

thanks,

-Christian

I know you want to make ELOG a stand alone program. But is there a way to still make a stand alone but have the option work with LDAP?
FYI
Elog works great we us it for our shift carryover and we have about 25 people useing it and I have heard no complants with it.
Thanks


I added your vote to the "PAM" authentication on the wishlist, since PAM contains an LDAP module.


Please Add my vote too. I think that would be great.

I had problems getting elog to run on port 8080 (or many others). I have it installed on Redhat Enterprise Linux rel 4. The only way I was able to get it working was using port 80. I would like to run it on a different port if possible but I'm not sure what is wrong.

Any Ideas

Is it possible to configure elog to copy a new entry from 1 logbook to another?

Nevermind. this was an iptables issue.

  1597   Tue Jan 17 14:09:17 2006 Question Chris Warnerchristopher_warner@dcd.uscourts.govQuestionLinux Email based on not attribute value
Is it possible to send an email if an attribute is not equal to a specific value?

For instance, I have a server logbook that several people are able to write to. There is one person that is ultimately responsible for this server. I would like to generate an email any time that someone other than the System Administrator creates a new entry.

Thanks,

Chris Warner

Users can access root level directories by using a modified URL. I saw on some security web sites that this was a problem in previous versions. Was it not fixed in 2.6?

To recreate enter http://yourhost.yourdomain.com/../../../../etc/passwd

view your password file in the browser.


If this was previously reported, is there a fix?

Thanks for telling me, I didn't know. I was able to reproduce your problem under certain conditions, and I just released version 2.6.1 to fix it. However it has nothing to do with an old buffer overflow (see elog:941).

I would strongly advise everybody to upgrade as soon as possible.


Thanks for the quick response!
