During system call execution, it is common for operating system kernels to read userspace memory multiple times (multi-reads). 6 and possibly earlier versions a race condition vulnerability exists in the sound system, this can lead to a deadlock and denial of service condition. A race condition occurs when two or more threads access shared data and try to do so at the same time. Several software vulnerabilities datasets for major operating systems and web servers are examined. I have a lab where I have to use this SeedUbuntu virtual machine for a race condition vulnerability. Race Condition Vulnerability. This paper describes RaceTrack, a dynamic race detection tool that tracks the actions of a program and reports a warning whenever a suspicious pattern of activity has been observed. This occurs when the system attempts to perform two or more requests at the same time depending on the sequence of the events [8]. Many vulnerabilities arise as a result of timing and sequencing, such as dependence on relative ordering, race conditions, synchronization, and deadlocks -- in both synchronous and asynchronous contexts. If you do this the right way, your payload sticks around in memory somewhere.
