This test case implements a time of check time of use vulnerability that allows arbitrary link following. The test case takes in a control file and an input file. The input file is checked to see if it is in the current working directory and not a symbolic link. If both of these conditions are tr...

This test case uses a counting semaphore initialized to one count of a shared resource to implement multiple unlocks of a critical resource for certain input. The test case takes a control integer, the names of two control files, and an input string. The control integer and the two control files ...

This test case implements a time of check time of use vulnerability that allows a DOS due to the input file being deleted before opening. The test case takes in a control file and an input file. The input file is checked to see if it is in the current working directory and exists. If both of thes...

This test case implements a single signal handler that is associated with two signals. The test case takes the names of two control files and an input string. The control files are used for timing within the test case to ensure that the test case follows an exploiting or benign execution path, an...

This test case implements a singleton struct without synchronization that can lead to two threads receiving separate instances of the singleton struct resulting in a deadlocked state. It takes a control integer, the names of two control files, and another integer as input. The control integer and...

This test case implements a singleton struct without synchronization that can lead to two threads receiving separate instances of the singleton struct resulting in a deadlocked state. It takes a control integer, the names of two control files, and another integer as input. The control integer and...

This test case implements two threads that lock a counting semaphore multiple times, causing a deadlock if the lock is locked more times that it is unlocked. The test case takes a string as input and if the input string contains spaces spawns two threads, the first of which locks a semaphore twic...

This test case implements a singleton struct without synchronization that can lead to two threads receiving separate instances of the singleton struct resulting in a deadlocked state. It takes a control integer, the names of two control files, and another integer as input. The control integer and...

C programs have two main options for mutual exclusion of a shared resource in a concurrent setting: the mutex lock and the semaphore. Mutex locks exist in two states, locked and unlocked. However a semaphore, more specifically a counting semaphore, can be used to keep track of an arbitrary number...

This test case implements a time of check time of use vulnerability that allows arbitrary link following. The test case takes in a control file and an input file. The input file is checked to see if it is in the current working directory and not a symbolic link. If both of these conditions are tr...

This test case implements two threads that do not use synchronization while accessing a shared resource. The test case takes a control integer, the names of two control files, and an input string. The control integer and the two control files are used for timing within the test case to ensure tha...

This test case implements a non-reentrant function that is called by a signal handler. The test case takes a control file and input string as input. The control file is used for timing and the input string is used as data for the test case to manipulate. The test case assigns a signal handler tha...

This test case implements two threads that lock a counting semaphore multiple times, causing a deadlock if the lock is locked more times that it is unlocked. The test case takes a string as input and if the input string contains spaces spawns two threads, the first of which locks a semaphore twic...

This test case takes the name of an externally accessible file as input, and treats the file as a global mutex lock. The test case will attempt to 'grab' the mutex lock by checking for the files existence, and creating it if it doesn't exist. The creation of the file is treated as grabbing the lo...

This test case implements two threads that each use a separate mutex lock object while accessing a shared resource. The test case takes a control integer, the names of two control files, and an input string. The control integer and the two control files are used for timing within the test case to...

This test case implements a missing lock check that allows two threads to access a shared character array simultaneously, leading to a null pointer deference. It takes an integer, the names of two control files, and an input string as input. The integer and two control files are used for timing, ...

This test case implements an asynchronous unsafe signal handler that access a string without properly null checking the pointer. The test case takes the name of a control file and an input string. The control file is used for timing within the test case to ensure that the test case follows an exp...
