Today I installed 0.105.0 to test the new fuzzy image signatures.
I was able to determine the fuzzy hash for a set of given pictures of
questionable content using:
sigtool --fuzzy-img pr0npic.jpg
Alas, I started up my trusty editor an generated an rezeptfrei.hdb
signature file containing:
pr0n1.jpg;Engine:150-255,Target:0;0;fuzzy_img#cb32363464cb5bca
pr0n1.jpg-2;Engine:150-255,Target:0;0&1;49484452;fuzzy_img#cb32363464cb5bca
and clamscan would bail with:
=============================
LibClamAV Error: cli_loadhash: Invalid value for the size field
LibClamAV Error: cli_loadhash: Problem parsing database at line 1
LibClamAV Error: Can't load /var/lib/clamav/rezeptfrei.hdb: Malformed database
LibClamAV Error: cli_loaddbdir: error loading database /var/lib/clamav/rezeptfrei.hdb
ERROR: Malformed database
I then tried the exact example from
https://blog.clamav.net/2022/03/clamav-01050-release-candidate-now.html
which reads:
--- snip ---
For example:
logo.png;Engine:150-255,Target:0;0;fuzzy_img#af2ad01ed42993c7
logo.png-2;Engine:150-255,Target:0;0&1;49484452;fuzzy_img#af2ad01ed42993c7
--- snip ---
alas, this one fails as well, with the same error message:
==========================================================
LibClamAV Error: cli_loadhash: Invalid value for the size field
LibClamAV Error: cli_loadhash: Problem parsing database at line 1
LibClamAV Error: Can't load /var/lib/clamav/rezeptfrei.hdb: Malformed database
LibClamAV Error: cli_loaddbdir: error loading database /var/lib/clamav/rezeptfrei.hdb
ERROR: Malformed database
So what IS the correct syntax?
