You can download the program and look it over without installing, it's
just bash scripts. It does appear in its own sigs directory there are
additional signature files:
-rw-r--r-- 1 root root 44
Here too: it took about 3 hours and 15 minutes to calm down (SPARC, Solaris 11,
v0.100.0)... without noticiable error in freshclam.log.

I also am seeing the same thing.
Killing freshclam an starting it again reproduces the process (and locks up
again).
You may have to delete daily.cld/cvd from your database directory in order to
get past this.
For those who are interested in the code, it is caught in a loop here:
https://github
Seems like this has been fixed.
Remove /var/lib/clamav/daily.* (either cld or cvd) and run freshclam again.
When freshclam failed to update, it was stuck on a .cld file. After removing
it, it downloaded daily.cvd and could be updated afterwards.

Pierre,
So you're saying it actually did finish after 3 hours, 15 minutes on its own?
That is good news for all of the automated systems, even if this is a
potentially terrible bug.
I'm still investigating the cause, and asking our signature management team if
they have any additional details
Yes Micah, it finished while I was checking the computer because of the
messages received
on the mailing list.

I confirmed with our signature management team that the extended time
processing daily-25380 is because this change is significantly larger than a
standard update.
This update drops 768053 hash-based signatures for malware that is detected by
other more efficient logical signatures. The net res
I'm not sure if the safebrowsing.cld is included in the daily cdiff, but
the current safebrowsing.cld takes between 50 and 70 seconds to *load* into
clamscan, where a copy from February loads in <5 seconds.

Henrik,
The reference file that we have for that signature appears to
contain CVE-2006-3227.
If you can share the file then use the FP reporting option <
http://www.clamav.net/reports/fp> to have the signature reassessed.
Thank you.

Maarten,
Thanks for reporting that. There is an ordering difference of the content
in the latest GDB file which is affecting the load time, and we will be
fixing that in the next safebrowsing CVD version.

For once (?) we're not having any problem with this update. Maybe it's
because we're still running 0.100.2?

I spoke too soon! Although 0.100.2 didn't hang, it did have to download
25380 several times -- while claiming success each time!

Hi Dave,
I noticed that the safebrowsing CVD was updated (I'm seeing version 48474
now) but the cdiff takes a VERY long time to apply and the new gdb file
takes about the same time to load.
Freshclam hangs at this point:
Wed Mar 6 16:03:05 2019 -> *Retrieving
http://db.US.clamav.net/safebrowsing
The new safebrowsing cvd (starting with version 48473) seems to be sorted
in a way that increases the load time of that file by several orders of
magnitude.
I have a previous version from February where the entries in the gdb
section are sorted like this:
S2:F:917787cff7b0993917209809ff3d94be
That's strange, the 48474 I have should have the sorting changed and has
the improved loading time we're talking about.

I have 48472 and 48473. The 48474 I got was the gdb file that was
downloaded as part of the cdiff. The freshclam process hung after
downloading though. The order of the 48474 gdb file was no different from
the order of the 48473 file.
Freshclam gets this far before hanging after the download. The

It's all in the ordering. We'll be keeping track of that going forward.
Safebrowsing 48474 is available from the mirror network now.

It's confusing in clamav because it's confusing everywhere. Those
