 | Stefano Lacaprara | stefano.lacaprara@pd.infn.it | Bug report | Linux | ELOG V3.1.3- | very long subject cause buffer overflow | Hi,
I'm using elog 313 on an ubuntu server.
A user inserted a very long subject by mistake (the text was supposed to go into the body, but he copy pasted in the wrong place).
This results in elogd crash with buffer overflow error when I try to look at the list of that elgbook.
I can reproduce it on my test server by copy pasting lorem ipsum in the Subject field of the demo elogbook. I'm not doing that here for obvious reason.
If I cut the length of the Subject in the *.log file by hand, all is back to normal.
Is there a way to protect from this problem in the front-end?
Thanks,
Stefano

 | Stefano Lacaprara | stefano.lacaprara@pd.infn.it | Bug report | Linux | ELOG V3.1.3- | Re: very long subject cause buffer overflow | Additional information: I tried to recompile with -g (debug) and run it in gdb but the crash is not reproduced that way (w/ or w/o gdb). I guess that the memory handling in debug mode is different so the corruption is not
there anymore.
Best,
Stefano

| Stefan Ritt | stefan.ritt@psi.ch | Bug report | Linux | ELOG V3.1.3- | Re: very long subject cause buffer overflow | Can you try to reproduce it on this (!) server? I cannot reproduce it on my home copy server, so I guess that might be fixed in meantime. Can you update to the current version of elog?

I've tried with elog-3.1.4-2 and git version, and I still have the same problem.
If I compile with make debug, it works.
Is there anything I can do to help debug the problem?
thanks for your help

| Stefan Ritt | stefan.ritt@psi.ch | Bug report | Linux | ELOG V3.1.3- | ... subject erased ... | I found two potential memory leaks which I fixed in the git version, so you can try again.
Another possibility, which is actually preferred, is to limit the size of the subject filed to a reasonable number. You can do that with following option
Format subject = 0, attribname, attribvalue, 80, 200
This shows the subject line with a width of 80 characters, but does only allow 200 characters to be entered there.
Best,

Just tested, and it works! Many thanks for very quick patch!

Yes, that is a good suggestion, I'll implemented it.
Many thanks again!
