Microsoft Windows 2000 and XP RPC race condition
| win-rpc-race-condition (13426) |  Medium Risk |
Description:
Microsoft Windows is vulnerable to a denial of service, caused by a multi-threaded race condition when handling Remote Procedure Call (RPC) requests. If two threads process the same request, memory corruption could occur, which would result in a denial of service. A remote attacker could send multiple RPC requests to cause the RPC service to crash.
Platforms Affected:
- Microsoft, Windows 2000
- Microsoft, Windows XP
Remedy:
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS05-051. See References.
Note: Microsoft originally provided a patch for this vulnerability in MS04-012, but it was superseded by the patch released with MS05-051.
For Windows 2000:
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS06-018. See References.
Note: Microsoft originally provided a patch for this vulnerability in MS04-012, but it was superseded by the patch released with MS05-051, and then superseded by the patch released with MS06-018. See References.
Consequences:
Denial of Service
