That's my interpretation, yes. I'm not really familiar with SILC,
though, so I could be wrong. That's a downside of us continue to
include a virtually unmaintained IM protocol :-(

Hmm. So you're saying a CVE pertains to a problem plus the associated
fix for that problem? I've always thought of them as pertaining only
to the problem.

Yeah I think that's accurate.

I'm pretty confident that the oscar fix is complete--I was pretty
thorough when investigating and writing the patch. (I should point
out that the oscar issue doesn't deal with private or channel
messages. It deals with authorization requests when adding ICQ
buddies to your list.)
