Hi all.
%uname -a
FreeBSD localhost 4.5-STABLE FreeBSD 4.5-STABLE #1: Tue Mar 12 08:20:11 CET

%cat syslog.c
#include <syslog.h>
#include <stdarg.h>
int main(int argc, char *argv[])
{
syslog(LOG_EMERG, argv[1]);
}
%./syslog "blah %x %x %x %x"
Message from syslogd@localhost at Mon Apr 29 23:27:35 2002 ...
localhost syslog: blah 2807aebe 2 bfbffc5c bfbffd26
Looks like we have a format string bug inside syslogd :)
