[orca-users:04208] 【重要】シスコ社製ルーターを使用中の施設へ
で情報提供しました内容に関する対策についての情報が参りました
ので、再度情報提供し足します。

Los Nettos will be upgrading IOS software on all their Cisco routers
and switches over the next few days.  The reloads will take place
during their normal maintenance window of 4AM to 6AM.

A public exploit was posted for this bug Friday, making it easy for
script kiddies all over the world to bring your unupgraded Cisco
routers to a screeching halt.  See CERT Advisory CA-2003-17
