Description Debian samba package maintainers (PUBLIC MAILING LIST) 2007-06-22 11:34:40 UTC
Hello,

this is a forwarded bug:

"While scanning our domain this morning I noticed that smbd will crash in
api_eventlog_open_eventlog (#4 in the backtrace below) when scanned by
Microsoft's Baseline Security Analyzer. I've marked this as minor because it
doesn't interfere with anything else.

I will try to reproduce this with the latest version of samba but maybe you already know something.

thx

Can you load a version with symbols so we can get a backtrace with line numbers please ?
Thanks,
Jeremy.
Comment 2 Jeremy Allison 2007-06-22 14:17:06 UTC
How are you recreating this ? I downloaded MBSA 2.0.1 and can't reproduce this. *Exactly* how are you configuring this ?
