Bell Labs, the R&D arm of Lucent Technologies, announced Thursday 
that it has released Libsafe, a new security software program for 
Linux. Libsafe prevents intruders from overloading an application's 
buffer memory to gain unauthorized access to a computer. (Located 
between two devices that have varying speeds for handling data, a 
buffer acts as a temporary storage unit or "dam," holding data and 
then disseminating it at a rate that will not flood the "lower 
banks.") According to a joint report by the Oregon Graduate Institute 
of Science and Technology and Darpa, buffer overflows or 
"stack-smashing attacks" have been the most common type of security 
exploit during the past 10 years.
