There is a separate Bug#888511 for that, I have migrated the fixed Version above to avoid confusion.<div><br></div><div>Are you sure about the Stretch thing? Stretch contains 0.99.2 which should be affected by this bug. But I’m not 100% sure, as all my high traffic mail gateways are still running Jessie.</div><div><br></div><div>According to reports 0.99.3~beta2 was indeed not affected by the signature bug, so Buster/Sid where fine. What makes things even more confusing is that 0.99.3 does not contain this fix, because 0.99.3 is 0.99.2+security fixes, while 0.99.3~beta was a development tree that is now called 0.100 :-(</div><div><br></div><div><a href="http://blog.clamav.net/2018/01/clamav-version-number-adjustment.html">http://blog.clamav.net/2018/01/clamav-version-number-adjustment.html</a></div><div><br></div><div>Upstream announcement suggests you cannot do a clean switch from 0.99.3~beta to 0.99.3</div><div><br></div><div><i style="background-color: rgba(255, 255, 255, 0);">As previously mentioned, if you downloaded the beta version of ClamAV 0.99.3, you will need to completely uninstall it and do a fresh install with the production version of 0.99.3 as there are significant code differences</i><br><blockquote type="cite"><span></span></blockquote></div><div><i style="background-color: rgba(255, 255, 255, 0);"><br></i></div><div><i style="background-color: rgba(255, 255, 255, 0);">Bernhard</i></div></body></html>
