Link Logger syslogd resource overwhelm DoS

Remote: yes

Vulnerable: 2.4.10.15 (ddwrt version) but more than likely all versions

Discussion:  Link Logger is a program for logging, analysis and reporting of 
router traffic so you can easily spot attacks and abuses on your network.  By 
sending a ton of spoofed traffic, the syslogd portion of link logger will 
become overwhelmed and crash.  The program must be restarted to bring syslogd 
back up.  After talking with the vendor, the syslogd portion is from another 
company, so other products may also be vulnerable.  The vendor would not 
disclose who the syslogd vendor was.

Log:
#Vendor notification 4/13/09
#Vendor acknowledgement 4/14/09, the syslogd is actually from another company, 
vendor contacts syslogd vendor.
#Vendor can not run DoS code successfully 5/11/09
#Sent instructions and video on how to install all needed modules and run 
successfully 5/12/09
#Asked for update, no response 6/8/09
#Sent to milw0rm and security focus 6/13/09

I will update this post when the code gets put on milw0rm.
