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 unchecked read from a buffer. The buffer is declared as a fixed size buffer as part of a struct on the heap. Untrusted input is not properly sanitized or restricted before being used as an index of the buffer to read. This allows inputs containing non-ascii characters...

This test case implements an sprintf that uses untrusted user input without a format string. The test case takes untrusted user input and passes it to an sprintf that does not implement a format string. This allows the user to pass format strings to the test case causing it to leak sensitive data...

This test case implements an unchecked read from a buffer. The buffer is declared as a fixed size member of a struct that is allocated 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...

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 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 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 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 implements an unchecked read from a buffer. The buffer is declared as a fixed size buffer as part of a struct on the stack. Untrusted input is not properly sanitized or restricted before being used as an index of the buffer to read. This allows inputs containing non-ascii character...

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 implements an unchecked write into a heap allocated buffer. The buffer is malloc'ed with a fixed size. Untrusted input is not properly sanitized or restricted before being copied into the target buffer, resulting in a buffer overflow. The overflow potentially modifies other variabl...

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 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 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...

This test case implements an unchecked write into a stack allocated buffer. The buffer is declared as a fixed size local variable within a function. Untrusted input is not properly sanitized or restricted before being copied into the target buffer, resulting in a buffer overflow. The overflow pot...
