[原文]NtRegmon before 6.12 allows local users to cause a denial of service (crash), while NtRegmon is running, via invalid pointers to hook functions such as ZwSetQueryValue.

[CNNVD]Sysinternals Regmon本地服务拒绝漏洞(CNNVD-200412-240)

        NtRegmon 6.12之前的版本存在漏洞。本地用户可以在NtRegmon正在运行时借助hook函数的无效指针(例如:ZwSetQueryValue)导致服务拒绝(崩溃)。

Sysinternals Regmon 6.11 Local Denial of Service Vulnerability (EDBID:24411)

Regmon is reported prone to a local denial of service vulnerability. This issue presents itself because the application fails to handle exceptional conditions and references unvalidated pointers to kernel functions.

Successful exploitation may allow a local unauthorized attacker to cause a denial of service condition in the application. The attacker may then obfuscate changes to the registry from the administrator and carry out further attacks against a vulnerable computer.

Regmon 6.11 for NT/9x and prior versions are reportedly affected by this issue.

- 漏洞描述

NtRegmon contains a flaw that may allow a local denial of service. When NtRegmon is running with privileges, any user can crash the system because NtRegmon doesn't properly check argument pointers supplied to ZwSetQureyValue kernel hook. This may result in a loss availability for the Windows machine.
