Hi All,

I have joined this list just know after see the reported issue  

Clamd service keep crashing with the following error code  

clamsmtp-clamd.service: main process exited, code=killed, status=11/SEGV

Kernel logs (dmesg) shows :

clamd[4053]: segfault at 7f081a3530bf ip 00007f0719f42960 sp 00007f06b5d12980 error 4 in libclamav.so.9.0.5[7f0719f04000+1e9000]


As per the above thread , we have tried to do the following , after this service is working fine. 

$ echo "Win.Downloader.LNKAgent-10001628-0" > /var/lib/clamav/bad_sig.ign2
Would like to understand , how did you find this is the issue ?


Regards
Seena

Same here......same version, but compiled from source directly......and the same strange message when clamd is restarted:

Starting clamd daemon: LibClamAV Warning: Don't know how to create filter for: Win.Downloader.LNKAgent-10001628-0
LibClamAV Warning: cli_ac_addpatt: cannot use filter for trie

Hello List,

since the update to version 26908 we observe a high amount of segfaults.

As far as I can tell this happens in

0x7fdfd44c377d <ac_backward_match_branch+813>

We use version 0.103.8+dfsg-0+deb11u1 on debian bullseye.

Has anyone seen this, too?

Best regards,
Matthias
