This test case implements an incorrect size check when reading from a buffer that can cause a buffer under read. The buffer is declared as a character buffer of size 64 on the heap. 64 bytes of input are copied into the buffer but the test case incorrectly uses the original size of the input stri...

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 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 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 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 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 ...

The buffer is declared as a character buffer of size 64 on the heap. 64 bytes of input are copied into the buffer but the test case incorrectly uses the original size of the input stri...

This test case implements a buffer that is used after it has been free()'d and it's memory allocated to another task. The test case takes a string as input and copies this string into an internal buffer allocated on the heap. For certain inputs (any string starting with an ASCII character with va...

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 implements a buffer that is used after it has been free()'d and it's memory allocated to another task. The test case takes a string as input and copies this string into an internal buffer allocated on the heap. For certain inputs (any string starting with an ASCII character with va...

This test case allocates a struct on the stack, with a 20-character buffer and a pointer following that buffer. It checks if the taint source is less than 20 characters. If so, it sets the 20-charcter buffer to all 0's then sets the pointer following the buffer to point to the beginning of the bu...

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 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 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 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 checks if the taint source is less than 20 characters, and if so, allocates a buffer on the heap with 20 characters. It sets the buffer to all 0's, then calls realpath on the taint source, with the destination being the 20-character heap buffer. If realpath evaluates to more than 2...

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 implements a buffer that is used after it has been free()'d and it's memory allocated to another task. The test case takes a string as input and copies this string into an internal buffer allocated on the heap. For certain inputs (any string starting with an ASCII character with va...

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 implements an improper array index validation that can cause a function pointer to get overwritten leading to a segfault. The test case takes untrusted user input and uses it to calculate array indexes which then get modified. If the untrusted input contains certain ASCII character...

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 incorrectly checked write into a buffer that is contained within a stack allocated struct. The buffer is declared as a struct member with a fixed size. Untrusted input is not properly sanitized or restricted before being copied into the buffer, from the last character...

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 stack, with a 20-character buffer and a pointer following that buffer. It checks if the taint source is less than 20 characters. If so, it sets the 20-charcter buffer to all 0's then sets the pointer following the buffer to point to the beginning of the bu...
