[原文]Integer signedness error in certain older versions of the NeL library, as used in Mtp-Target 1.2.2 and earlier, and possibly other products, allows remote attackers to cause a denial of service (memory consumption or server crash) via a negative value in a STLport call, which is not caught by a signed comparison.


[CNNVD]Mtp-Target Server内存损坏漏洞(CNNVD-200505-859)

        NeL库某些旧版本在用于Mtp-Target 1.2.2及更早版本以及可能的其他产品上时存在整数符号错误,远程攻击这可以通过一个不能被有符号比较所捕捉的在STLport调用中的负数值,发起拒绝服务攻击(内存损耗或服务器崩溃)。

Mtp Target NeL Library STLport Remote DoS
Remote / Network Access Denial of Service
Loss of Availability
Exploit Public

- 漏洞描述

A remote overflow exists in Mtp Target. The NeL library fails to verify if the amount of memory to allocate, a user-supplied integer parameter, is less than 1,000,000 bytes. With a specially crafted request containing a negative value, an attacker can cause the server to allocate a large amount of memory through a call to STLport, resulting in a loss of availability of the server process.

- 受影响的程序版本

Mtp-Target Mtp-Target 1.2.2

- 漏洞讨论

The Mtp-Target server is prone to a memory corruption vulnerability. The issue exists because a comparison fails to ensure that an integer value parameter retrieved from a client is signed. A check is made to ensure that the user-supplied value is less than 1000000 bytes. If the value passed is FFFFFFFFh, it is interpreted as a signed -1 and the check passes. The value is later used as an unsigned integer in a memory allocation operation. An allocation of 4.29 GB of data is attempted and the service crashes.

Immediate consequences of exploitation of this vulnerability are a denial of service.
