Improper Locking

Overview Affected versions of this package are vulnerable to Improper Locking in the releasewritelock and releasereadlock functions. An attacker can disrupt synchronization guarantees and exploit data races or cause denial of service by invoking these functions from unauthorized threads or withou...

Wrap-around Error

Overview Affected versions of this package are vulnerable to Wrap-around Error in ReentrantReadWriteLock that causes incorrect write locks. An attacker can cause a thread to incorrectly obtain a write lock without exclusivity by repeatedly acquiring the read lock 32,768 times, which overflows the...

Concurrent Ruby - ReadWriteLock allows wrong-thread write release and stray read-release counter corruption

Summary Concurrent::ReadWriteLockreleasewritelock does not verify that the calling thread acquired the write lock. Any thread with access to the lock object can release an active write lock held by another thread. A second writer can then enter its critical section while the first writer is still...
