[原文]Buffer overflow in Pico Server (pServ) 2.0 beta 1 through beta 5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) a 1024-byte TCP stream message, which triggers an off-by-one buffer overflow, or (2) a long method name in an HTTP request, (3) a long version number in an HTTP request, (4) a long User-Agent header, or (5) a long file path.


[CNNVD]Pserv流读取缓冲区溢出漏洞(CNNVD-200212-546)

        Pico Server (pServ) 2.0 beta 1版本到beta 5版本存在缓冲区溢出漏洞。远程攻击者可以借助(1)触发一位偏移缓冲区溢出的1024字节TCP流消息,或(2)HTTP请求的超长方式名,(3)HTTP请求的超长版本号,(4)超长User-Agent标题,或(5)超长文件路径导致服务拒绝(崩溃)并且可能执行任意代码。

A buffer overflow vulnerability has been reported in Pserv. The buffer overflow condition is due to the way Pserv handles data streams from remote connections. 

An attacker can exploit this vulnerability by issuing a HTTP request with an invalid HTTP version specifier. Due to insufficient buffers being allocated when processing the data, it may be possible to corrupt sensitive memory on the system stack.

GET / HTTP/1.[buffer]
