To: BUGTRAQ@SECURITYFOCUS.COM

ZDnet http://www.zdnet.com/zdnn/stories/news/0,4586,2675147,00.html and
MSNBC http://www.msnbc.com/news/517622.asp?0cm=c20 have been reporting a
new Linux worm today, highly similar to the Morris worm.  Curiously,
Bugtraq has been silent on this issue, but securityfocus.com now has a
good technical article up http://www.securityfocus.com/news/139

Upon reading the Securityfocus article, we found that all three of the
attacks used by Ramen are stopped by FormatGuard
http://immunix.org/formatguard.html

   * WU-FTPD format bug
     http://www.securityfocus.com/vdb/bottom.html?vid=1387
   * rpc.statd format bug
     http://www.securityfocus.com/vdb/bottom.html?vid=1480
   * LPRng format bug
     http://www.securityfocus.com/vdb/bottom.html?vid=1712

 Therefore, Immunix System 7 is invulnerable to Ramen.
