Re: [clamav-users] Bytecode run timed out in interpreter after 5000 opcodes
Hi Ralf,
There are 3 bytecode rules for detecting CVE's that seem to take a rather long
time to run, particularly as the file grows in size. I'm discussing with our
threat research team if we can remove them as CVE's are old enough that no one
should reasonably still be affected by the vulnerabilities.
I am curious though - what are your MaxFileSize / MaxScanSize settings? I
wonder if you're seeing timeouts with the default settings or if you increased
them.

is this a bad Bytecode rule?

That has not worked for me in the past. If there is a way to comment out
signature lines, I've not discovered it.

Re: [clamav-users] Bytecode run timed out
It looks like this one that gives the "Bytecode run timed out" warning. I'm
trying the other two as well.
BC.Multios.Exploit.CVE_2017_2816-6329916-0.{}
Plus, there's a new bytecode exploit that seems to be giving me a lot of
positives:
BC.Pdf.Exploit.CVE_2017_3032-6316401-6
I've put that (with the trailing '.{}') in the .ign2 file as well.
Can I use a '#' at the beginning of the lines in the .ign2 file as a comment?
I've found no documentation on this and, if not, I might be getting false
results.

Yes, I was able to find the file as well. I've used the syntax in the
/var/lib/clamav/local.ign2 file recommended by Al Varnell:
BC.Multios.Exploit.CVE_2017_2816-6329916-0.{}
BC.Pdf.Exploit.CVE_2017_2818-6331913-0.{}
BC.Pdf.Exploit.CVE_2017_2862-6331914-0.{}
and that worked to block the warning. Now I will test each one in turn to see
which bytecode is causing the message.

Re: [clamav-users] Bytecode run timed out
I have been noticing the same issue. I found at least one file that was
causing the error, and was able to test with a single file, instead of
having to virus scan an entire directory tree to test.
LibClamAV Warning: [Bytecode JIT]: Bytecode run timed out, timeout flag set
LibClamAV Warning: [Bytecode JIT]: recovered from error
LibClamAV Warning: [Bytecode JIT]: JITed code intercepted runtime error!
LibClamAV Warning: Bytcode 64 failed to run: Time limit reached
This worked for me:
# cat /var/lib/clamav/local.ign2
BC.Pdf.Exploit.CVE_2017_2818-6331913-0.{}
The problem file was the one listed under the JIT error messages, in my
case, it was a pdf file that caused it.

I suspect you'll want to try one at a time to nail down which signature is
causing the problem.
Checking back I see there was a period rather than a space between the
signature name and the brackets, so:
BC.Multios.Exploit.CVE_2017_2816-6329916-0.{}

This is a pretty recent phenomenon. Perhaps something introduced in a recent
update. I received bytecode.cld version 306 in freshclam starting on July 16,
2017; which is exactly when I started seeing this warning. I did not get the
warning with version 305.
Is this a bug?
For now, I guess I'll just have to live with it.

It's my understanding that not all files receive a bytecode signature scan,
making it even more difficult to determine the problem file.

These are Maildir format files. The "S=12386" part is in fact the file size.
It's not apparent from where the Warning message is issues what file is causing
the warning. The 12,657 byte file couldn't have been it and why would the
1,266,193 size file cause the warning and not the more that twice-as-large file
immediately following? Also there are much larger files in this directory, up to
21M, but this is the only warning issued.

Re: [clamav-users] Bytecode run timed out
I ran clamscan by hand on the files before and after the error, and it's the file after the error. I've bumped the --bytecode-timeout to 12, 18 and finally 60 (10 minutes) and it fails for all these values, even though the file itself is not that big (1.2M). This is a pretty recent phenomenon. Perhaps something introduced in a recent update. I received bytecode.cld version 306 in freshclam starting on July 16, 2017; which is exactly when I started seeing this warning. I did not get the warning with version 305. Is this a bug? For now, I guess I'll just have to live with it.

Re: [clamav-users] Bytecode run timed out
It's almost certainly a file that follows S=12386 since that one is being reported as "OK". The file that failed might not even be listed, having failed the scan, although I suppose it's possible for it to be the next one shown. It's my understanding that not all files receive a bytecode signature scan, making it even more difficult to determine the problem file. -Al- On Fri, Jul 21, 2017 at 08:59 AM, Mark Foley wrote: > > Here's the partial output from clamscan w/o the --infected option: > > /home/HPRS/charmaine/Maildir/.INBOX.Audit-CAFR-OBM/cur/1424057307.M683247P23198.mail,S=12386,W=12657:2,RS: > OK > LibClamAV Warning: [Bytecode JIT]: Bytecode run timed out, timeout flag set > LibClamAV Warning: [Bytecode JIT]: recovered from error > LibClamAV Warning: [Bytecode JIT]: JITed code intercepted runtime error! > LibClamAV Warning: Bytcode 5 failed to run: Time limit reached > /home/HPRS/charmaine/Maildir/.INBOX.Audit-CAFR-OBM/cur/1424057400.M645852P23198.mail,S=1266193,W=1282921:2,S: > OK > /home/HPRS/charmaine/Maildir/.INBOX.Audit-CAFR-OBM/cur/1490619717.M352662P13554.mail,S=3456056,W=3506158:2,S: > OK > > These are Maildir format files.

Re: [clamav-users] Bytecode run timed out
It doesn't give any file names, even in the logfiles. It happens when I'm running clamscan. I am running it on lots of files, 124,681 to be exact (IMAP mail files). What is the default for --bytecode-timeout? If I get it again I'll increase it.

Re: [clamav-users] Bytecode run timed out
When ClamAV runs bytecode signatures, it uses a timer to limit the amount of processing. Are you seeing it on a lot of files? If that is the case, the bytecode signature may require attention. You can try increasing the timeout limit. --bytecode-timeout for clamscan and BytecodeTimeout for clamd. Steve On Thu, Jul 20, 2017 at 9:47 AM, Mark Foley wrote: > What is this?

Lets try something else then.
It says here that bytecode 3 failed to run:
>> LibClamAV Warning: Bytcode 3 failed to run: Unknown error code
Run this to find out what is the name of bytecode 3:
$ clamscan --debug /dev/null 2>&1|grep 'cbc(3)'
For me it says (but it might depend if you have cvd or cld):

I ran: /usr/local/bin/clamscan -rv --bytecode-timeout=1 /home It didn't produce any errors this time. Maybe a recent update of the signature database fixed this?

(run clamscan -v to see what file it is scanning) Then please open a bug and attach the file. Meanwhile you can try setting the timeout lower, using --bytecode-timeout/BytecodeTimeout (it is 6 ms by default).

[clamav-users] Bytecode run timed out
Hi, Since two days, I'm getting lots of these messages while scanning one of the servers here: LibClamAV Warning: [Bytecode JIT]: Bytecode run timed out, timeout flag set LibClamAV Warning: Bytcode 3 failed to run: Unknown error code This is on FreeBSD-8 with ClamAV 0.97.3/14583/Mon Mar 5 01:34:31 2012. This brings scanning this server to a crawl, unfortunately, so I had to kill the nightly scans. Does this indicate a problem in the signatures, or is there a problem with the local scanner?
