[原文]Multiple "buffer management errors" in OpenSSH before 3.7.1 may allow attackers to cause a denial of service or execute arbitrary code using (1) buffer_init in buffer.c, (2) buffer_free in buffer.c, or (3) a separate function in channels.c, a different vulnerability than CVE-2003-0693.

[CNNVD]OpenSSH 缓冲区管理错误漏洞(CNNVD-200310-010)

        OpenSSH 3.7.1之前的版本存在多个“缓冲区管理错误”。攻击者使用(1)buffer.c的buffer_init,(2)buffer.c的buffer_free,或者(3)channels.c的separate函数导致服务拒绝或者执行任意代码,该漏洞不同于CVE-2003-0693。

- 漏洞描述

OpenSSH contains several flaws that may allow remote attackers to execute arbitrary code. The issues occur in the buffer_init and buffer_free functions in buffer.c, as well as an separate function also called buffer_free in channels.c. These functions may provide an attacker with the opportunity to inject custom data that could result in memory manipulation and possibly code execution.
