Segfautls with : 0.88.1-1ubuntu1

[Patrick Ancillotti]

Hi,

I'm using clamd with clamsmtp on amd64, i seem to get segfaults with clamd, any ideas? 0.88 doesn't seem to do the same.

current safe release : ClamAV 0.88/1408/Wed Apr 19 17:13:11 2006

If you'd like any more information, please pop me a mail or so.

Hello and thank you for your bug report. When does it crash? Can you provide steps to reproduce the problem? Could you please try to obtain a backtrace according to http://wiki.ubuntu.com/DebuggingProgramCrash ? Are you running Dapper (with all updates) ? Thanks.

Hi there,

Sorry about the delay in replying, the problem is created randomly when the clamd is in production, now the reason i say production is because it happens after clamsmtp's run a few scans, although they're not always after the same ammount of scans, nor the same ammount of time.

Also the reason i know it's clamd is that in the /var/log/clamav/clamav.log i get a segfault message with a smiley face. I'll work on the backtrace for you, but i've gotta work out how to do it first though :)

Hi,

Working on the program crash for you, although after upgrading to the next release of the package ( -1ubuntu2 i believe ) the problem's still floating, yes it is dapper with all the updates.

Will update in a short while with the required info.

Hi,

Here's the GDB output, seems to be a zziplib related problem.

One last thing i'd like to add, i've just installed the clamav from :

deb http://ftp.debian.org/debian unstable main non-free contrib deb-src

Which would be :

clamav-base_0.88.2-1_all.deb
clamav-daemon_0.88.2-1_amd64.deb
clamsmtp_1.6-1_amd64.deb
clamav-freshclam_0.88.2-1_amd64.deb

And they don't segfault on the same machine.

And again, i'd assume this has somthing to do with it :

from :

    - libclamav/zziplib/zzip-zip.c: add missing #include "others.h"
      Patch by Alex Deiter <tiamat*komi.mts.ru>

Any idea on when 0.88.2 would be in ubuntu?

Hi, thanks for the great work on the bug. I'm not at home as of now so I can't really take a look at the changes between 0.88.1 and 0.88.2 . According to #42568 it's likely that in a few days 0.88.2 will be in the dapper repositories (you shouldn't be installing debian packages btw). When I get home I'll take a look at what changes have taken place, but at first glance it doesn't seem that adding the include will make a difference. Thanks again.

Hey,

Thanks for the quick reply.

I kinda figured you'd have your 'ear' to the ground more than myself in regards to when the next release of clam would be in the dapper repo's.

( i don't as a habbit install debian packages, although i figured it wouldn't hurt me to test it, and it fixed the problem, as well as lead to another interesting find, the ``others.h`` thing. )

I can however tell you that i've added the 'others.h' include line, and as of now, i've been running ( after re-building the source for 0.88.1 as per the Program Crash bits... ) for about 45 minutes without a crash, as the 0.88.2 version from the debian upstream did.

The GDB crash specifically mentioned a call in zzip-zip.c, so i'm assuming after my test ( recompile with include ) and after the note in the changelog, i'd assume it would be a safe bet... Would one bother writing a patch to update 0.88.1 to include that 'others.h' ?

Hi,
it appears that many have had similar problems and your solution is the correct one.

I'm not a developer, I'm just triaging bugs so I know just as much as the next person :)

[Patrick Ancillotti (patricka)]

Hey,

Ok, Great...

So would one write a patch for 0.88.1? Or just wait till 0.88.2 arrives?

Also, bug-status change please ;)

P

[Vassilis Pandis (pandisv)]

Well it seems that the sync with debian is going to happen in the next few days (I'm not involved with this so I can't give any promises) so I don't think somebody will upload the patch for 0.88.1 . Please be patient :) Thanks.

[Patrick Ancillotti (patricka)]

Hey,

thanks for the response, no huge rush, it's working right now my whole home-brew edition.

Thanks again Vassilis.

0.88.2 is the current version, changing the status. If this persists, please reopen the bug. Thanks for looking into this.
