[原文]Computer Associates (CA) eTrust Intrusion Detection 3.0 allows remote attackers to cause a denial of service via large size values that are not properly validated before calling the CPImportKey function in the Crypto API.


[CNNVD]CA eTrust入侵检测系统CPImportKey拒绝服务漏洞(CNNVD-200505-071)

        远程利用CA eTrust入侵检测系统中的漏洞可能允许攻击者导致拒绝服务。
        漏洞的起因是对Microsoft的加密API函数CPImportKey所传送的值执行了不充分的检查。CPImportKey函数通过传送给CPImportKey的数据blob中所提供的数据来确定某些缓冲区分配的大小,因此如果包装函数在调用CPImportKey前没有验证传送给Crypto API的数据的话,就可能导致分配很大的缓冲区。如果CPImportKey所收到的大小值超过了映射的内存大小,就可能发生异常,不释放内存。 特制的报文可能耗尽所有可用的内存资源,造成拒绝服务。这样网络的入侵检测功能就会失效,导致进一步的攻击。

- 漏洞讨论

eTrust Intrusion Detection System is reported prone to a remote denial of service vulnerability.

This vulnerability specifically arises due to the improper use of the Microsoft Crypto API function called 'CPImportKey'. eTrust Intrusion Detection System employs the Microsoft Crypto API functionality without wrapper functions to validate user-supplied input and is susceptible to denial of service attacks.

A successful attack can crash the application by exhausting memory resources. This can facilitate further attacks against the network and the possibility of attacks not being detected.

eTrust Intrusion Detection System 3.0 and 3.0 SP1 are reported vulnerable.
