[原文]Intel RNG Driver in NetBSD 1.6 through 3.0 may incorrectly detect the presence of the pchb interface, which will cause it to always generate the same random number, which allows remote attackers to more easily crack encryption keys generated from the interface.


[CNNVD]NetBSD 错误Intel硬件RNG检测可预测随机数产生漏洞 (CNNVD-200604-304)

        NetBSD 1.6 至3.0中的 Intel RNG Driver不能正确地检测pchb接口的存在,这导致一直生成相同的随机数。该漏洞允许远程攻击者更容易地破解由该接口产生的加密密钥。

NetBSD Intel Hardware Random Number Generator (RNG) Failure Encryption Weakness
Local Access Required Cryptographic, Information Disclosure
Loss of Confidentiality
Exploit Unknown

- 漏洞描述

NetBSD contains a flaw that may reduce the quality of random numbers used when encrypting data. The issue is triggered by incorrectly detecting the presence of Intel's 'pchb' random number generator when it is not in fact present. It is possible that the flaw may allow a reduction of quality of random data used by encryption mechanisms resulting in a loss of confidentiality.
