clamscan can't detect malware inside a debian package
Hello,

I've made a few tests lately to embed malwares inside UNIX packages like
RPM or DEB packages. Once done, I scanned the packages with many
anti-virus products to check their efficiency.

Concerning clamav, there was no problem finding malware embedded into a
RPM package. Nevertheless clamscan was unable to detect a known malware
(the C99 PHP Backdoor) added to a preinst or postinst file.

Should I report this as a bug ?

Regards

Just published bytecode.cvd version 138, is the .deb detected now?

(Run freshclam, make sure you get bytecode.cvd 138, and that you run
0.96.4+)

Best regards,
