Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Race condition in the SMB client implementation in Microsoft Windows Server 2008 R2 and Windows 7 allows remote SMB servers and man-in-the-middle attackers to execute arbitrary code, and in the SMB client implementation in Windows Vista Gold, SP1, and SP2 and Server 2008 Gold and SP2 allows local users to gain privileges, via a crafted SMB Negotiate response, aka "SMB Client Race Condition Vulnerability."
CWE-362 - Race Condition
A race condition occurs in a shared memory program when two threads/processes access the same shared memory data, and at least one thread executes a write operation. This vulnerability manipulates the time to check vs. time to use (TOC/TOU) gap between the threads in the critical section to cause disorientation in the shared data. The impact can vary from compromising the confidentiality of the system to causing the system to crash or to execute arbitrary code.
