CWE-1096 在没有正确锁定或同步的情况下创建单实例类实例

Singleton Class Instance Creation without Proper Locking or Synchronization

结构: Simple

Abstraction: Variant

状态: Incomplete

被利用可能性: unkown

基本描述

The software implements a Singleton design pattern but does not use appropriate locking or other synchronization mechanism to ensure that the singleton class is only instantiated once.

扩展描述

This issue can prevent the software from running reliably, e.g. by making the instantion process non-thread-safe and introducing deadlock (CWE-833) or livelock conditions. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability.
