Hi,

I'm using clamav-0.103.8 on fedora37 with the current daily update and have
received a false positive involving the RPMSG secure download that's
apparently part of office365.

For some reason the fp is in the body of the message, not the
message_v2.rpmsg attachment. Here is the entire message:
https://drive.google.com/file/d/1ZImepnB_U5_pI0CXRhWm8nlKVCPCFnw3/view?usp=sharing

Here's the sigtool output. Is this in fact a false positive?
