Unsafe library function calls
•A library is a
collection of useful subroutines that a programmer
can use in their program.
•The standard C library,
which every C compiler has, has subroutines in
it that can cause buffer overflows if not used properly.
•Programmers have to
learn to use the library subroutines properly. Unsafe library function calls are
responsible for many vulnerabilities of
all types.
