This test case implements an file read of 128 characters which does not properly null terminate the copied string if the original string is 128 characters in length or greater. The test case takes the name of a file, opens the file, and reads up to the first 128 characters into an internal buffer...

This test case creates a struct that has a message_type field and a message_data field. The message_type field should be 1 if the message_data field contains a char*, and 0 if it contains an int. The message_data field is set to be the taint source, and the message_type field is set to 1. If the ...

This test case allocates a buffer on the heap, copies the input string into it, and then capitalizes each letter in the buffer. It searches that buffer to see if it contains the letter 'E', using a while loop that increments the pointer to the buffer each time through the loop. When it finds a le...

This test case implements an file read of 16 characters which does not properly null terminate the copied string if the original string is 16 characters in length or greater. The test case takes the name of a file, opens the file, and reads up to the first 16 characters into an internal buffer of...

This test case takes a buffer as input and copies it into another buffer. It then converts the new buffer to uppercase and prints it out. If the provided input is larger than the buffer it is being copied into, then this will result in a buffer overwrite due to access with an incorrect length. Th...

This test case creates a struct on the stack that contains a function pointer and a char*. It examines the length of the taint source. If the length is not equal to 10, it sets the function pointer and char* within the struct to benign values. If the length is equal to 10, it does not set the fun...

This test case creates a function pointer that takes 2 const char * as input and returns an int. If the length of the taint source is 0 mod 3, the test case sets the function pointer to be strcmp. If the length of the taint source is 1 mod 3, the test case sets the function pointer to strcoll. Ot...

This test case creates a buffer on the stack of 1024 bytes and a struct on the heap containing a 64-byte buffer and a pointer to the beginning of that buffer. It copies the taint source into the 1024-char buffer. It checks if the length of the taint source is less than the length of the 64-byte b...

This test case implements an file read of 128 characters which does not properly null terminate the copied string if the original string is 128 characters in length or greater. The test case takes the name of a file, opens the file, and reads up to the first 128 characters into an internal buffer...

This test case creates two buffers on the stack, one of 64 bytes and one of 1024 bytes. It copies the taint source into the larger buffer. It checks if the length of the taint source is less than the length of the shorter buffer. If it is, it uses strncpy to copy the taint source into the shorter...

This test case implements an unchecked read from a buffer. The buffer is declared as a fixed size buffer on the stack. Untrusted input is not properly sanitized or restricted before being used to determine the number of characters to read from the buffer. This allows input greater than 63 charact...

This test case allocates a buffer on the stack, with a canary function pointer immediately after it. It checks if the taint source is less than 20 characters, and if so, it sets the canary function pointer to strlen and call realpath on the taint source, putting the result into the stack buffer. ...

This test case implements an file read of 16 characters which does not properly null terminate the copied string if the original string is 16 characters in length or greater. The test case takes the name of a file, opens the file, and reads up to the first 16 characters into an internal buffer of...

This test case implements an unchecked write into a buffer that is contained within stack-allocated struct. The struct contains a function pointer, a fixed-size buffer, and another function pointer. Untrusted input is not properly sanitized or restricted before being copied into the target buffer...

This test case implements an unchecked read from a buffer. The buffer is allocated as a fixed size buffer on the heap. Untrusted input is not properly sanitized or restricted before being used to determine the number of characters to read from the buffer. This allows input greater than 63 charact...

This test case creates a struct that has a message_type field and a message_data field. The message_type field should be 1 if the message_data field contains a char*, and 0 if it contains an int. The message_data field is set to be the taint source, and the message_type field is set to 1. If the ...

This test case creates a buffer on the stack of 1024 bytes and a struct on the stack containing a 64-byte buffer and a pointer to the beginning of that buffer. It copies the taint source into the 1024-char buffer. It checks if the length of the taint source is less than the length of the 64-byte ...

This test case creates a buffer on the stack of 1024 bytes and buffer on the heap of 64 bytes. It copies the taint source into the 1024-char buffer. It checks if the length of the taint source is less than the length of the 64-byte buffer. If it is, it uses strncpy to copy the taint source into t...

This test case creates two buffers on the stack, one of 64 bytes and one of 1024 bytes. It copies the taint source into the larger buffer. It checks if the length of the taint source is less than the length of the shorter buffer. If it is, it uses strncpy to copy the taint source into the shorter...

This test case allocates a struct on the heap that contains an 8-character buffer, followed by a pointer. The pointer is set to point to the beginning of the 8-character buffer. The taint source is copied into the 8-character buffer, using strncpy, but the length is incorrectly capped at the leng...

This test case implements a heap allocated buffer that erroneously gets double free()'d causing a segfault. The test case takes an input string and copies it into a heap allocated buffer. It then checks to see if the first character is an 'a' or greater and if so, calls a function that finishes b...

This test case implements stack allocated buffer which, under certain inputs, gets erroneously free()'d. The test case takes a string as input and copies it to an internal array of size 64 allocated on the stack. This string is the converted to all caps and, if the resulting string's first letter...
