![]() And then the Stack smashing error is seen. The output seems OK, and the print of "test" at the end of the code prints. ![]() While(-1 != getline(&buffer3,&buffer_size,Names)) The new blank drive is exactly the same 3TB WD purple, just 5 years newer. Still works in the roamio, so Im trying to keep all my shows. For example in the following snippet: The compiler, (in this case gcc) adds protection variables (called canaries) which have known values. stack smashing detected : terminated Aborted I installed the original 3TB WD purple drive 5 years ago and its just now starting to studder (/dev/sda). While(-1 != getline(&buffer,&buffer_size,Dictionary)) Stack Smashing here is actually caused due to a protection mechanism used by gcc to detect buffer overflow errors. ROP into the code that returns from a system call and continues execution in user space.ROP to change the current creds to UID 0.Stack smash and overwrite the canary and return address to trigger a ROP chain.Names = fopen ("/home/overdog/Documents/Coding/rawnames.txt","r") The attack can be split up into a number of stages: but i get a stack smashing detected error at the very end of code.Ĭode is : void main (int argc, char *argv)Ĭhar *buffer =malloc(buffer_size * sizeof(char)) Ĭhar *buffer2 =malloc(buffer_size * sizeof(char)) Ĭhar *buffer3 =malloc(buffer_size * sizeof(char)) Ĭhar *buffer4 =malloc(buffer_size * sizeof(char)) ĭictionary = fopen ("/home/overdog/Documents/Coding/dictionary.txt","r") I cannot seem to find why this is stack smashing, the code is meant to read in some files, read each line and cat other lines on the end.
