[2.0.0] xml errors in the log

I often see this error message in the log:

Thanks for your report. This message was caused by a single VT added to the feed recently which had a special control char in the "affected" tag. This special char has already been removed and the updated VT should be included in one of the next feed updates, in addition the ospd-openvas is getting improved to handle such special chars more gracefully:
