[原文]Heap overflow in the KTH Kerberos 4 FTP client 4-1.1.1 allows remote malicious servers to execute arbitrary code on the client via a long response to a passive (PASV) mode request.


[CNNVD]KTH eBones Kerberos4 FTP客户端被动模式堆破坏漏洞(CNNVD-200206-006)

        KTH FTP客户端是一款免费的实现对Kerberos4 eBones支持的程序,可使用在Unix和Linux操作系统下。
        KTH eBones Kerberos4 FTP客户端对服务器响应其被动模式请求的数据处理存在漏洞,可导致堆破坏,使攻击者以ftp进程权限在目标系统上执行任意命令。攻击者可以伪造服务器数据,当客户端提交被动模式请求,服务端如果以超长的字符串代替IP地址和端口数据发送给客户端,客户端在解析此响应时可导致堆破坏,精心构建此数据可使攻击者以FTP进程的权限在目标系统上执行任意命令。

4897
KTH Kerberos 4 FTP Client PASV Execute Arbitrary Code
Remote / Network Access Input Manipulation
Loss of Integrity

- 漏洞描述

A remote overflow exists in KTH Kerberos 4 FTP Client. The FTP Client fails to do proper bounds checking while receiving a server response to a client request for passive mode, resulting in a heap overflow. By impersonating an FTP Server, an attacker can trigger the overflow on the FTP Client, resulting in a loss of integrity.

- 漏洞讨论

This problem affects the ftp client source included with the Kerberos4 eBones implementation maintained and distributed by KTH. It is also part of the default installation of SuSE Linux. It is freely available. This vulnerability affects only Unix and Linux operating systems.

Under some circumstances, it may be possible to take advantage of a heap overflow in the ftp client. Insufficient bounds checking is in place when processing the server response to a client passive mode request. A server response of excessive length may result in heap overflow condition.
