[Saurabh Ahuja]

Refer https://vulncat.fortify.com/en/detail?id=desc.internal.cpp.buffer_overflow_off_by_one

Code Snippet:

line[0] = '\n';
while (fgets(line+1, buffer_size, fp_find))
{
if (strstr(list_target, line) == NULL)

This code is susceptible to buffer overflow as reflected in above wiki. Can you please provide solution for same?
