Complaints about vulnerability to Ping of Death attacks over the past month have prompted Microsoft and a handful of other vendors to release patches to their products.
The Ping of Death, discovered in early October, is a denial-of-service attack that crashes network servers or firmware by overloading them with illegally large ping packets. Over the past few weeks Microsoft, Bay Networks, Galacticomm, Storage Technology and the Linux community have been among those issuing patches.
Microsoft has developed a new version of its ping.exe file that will not allow users to send illegally large ping packets. Bay issued patches for its routers, Galacticomm released patches for the TCP/IP kernel in Versions 1 and 2 of its Worldgroup BBS software, and the community of developers that supports and updates the Linux freeware operating system has also posted patches.
Storage Technology's Network Systems Group released a Net Sentry security module that blocks packets with inappropriately large amounts of data.
