This test takes a filename that is used as a representation of an externally accessible and unrestricted mutex lock. The weakness will then attempt to grab this lock by checking for the files existence, and creating the file if it doesn't exist. If the file does exist, the weakness will hang unti...

This weakness takes in an integer and string "int string" where the integer is the size of the array to sort for timing and the string contains the value that is acted upon by the treads, stored in a global static variable. A divide by zero error occurs when the string starts with 'A' and the arr...

This test takes a string. It locks a lock upon encountering the first '1' in the string, then locks the lock each time it subsequently encouters another '1'. If there are three or more '1' characters in the string, this will cause multiple locks and an unexpected state (DOS). Metadata - Base pro...

This weakness takes an input of "<qsize> <string>" where qsize is the length of the array to generate and sort for timing and string is an arbitrary string to use as data to pass around. The weakness uses a double checked lock to initialize a shared static data class in an attempt to be efficient...

This test takes an integer followed by a filename as input (int filename), and checks that the file exists, is in the current directory, and is not a symbolic link. However the weakness takes some time before opening the file allowing a time of check, time of use vulnerability. This vulnerability...

Algorithmic variant: basic Root cause: none This test takes a string. If the first letter is a lower case letter, the main thread will get a lock guarding an integer, and count the number of lower-case letters into that integer. A second thread will get a lock guarding a second integer, and will...

This weakness takes an integer and string as input (int string) where the integer is the size of the array to sort for timing and the string is the data that is acted upon. The weakness spawns two threads, both of which in turn call the function 'arrFunc' which is non-reentrant. 'arrFunc' uses a ...

This weakness takes an integer, two file names, and an integer "int file1 file2 int" as an input. The first integer is the size of the array to sort for timing in benign cases without FIFO files as inputs. The two files are used for thread "scheduling", if they are FIFO files in the order "fifo1 ...

This test takes a string. It locks a lock upon encountering the first a/A in the string, using one lock for lower case a and a different lock for upper case A. Upon encountering a second a/A in the string, it unlocks the lower case lock. If an A appears before an a, then the lock is unlocked with...

This weakness takes a string in the form: '<qsize> <data>' where qsize is the size of the array to sort (used to delay execution) and data is a string that is used for processing. The contents of this string are unimportant. Two threads are created, one of which fails to check for a mutex lock le...
