descriptionBUGTRAQ ID: 30697 CVE(CAN) ID: CVE-2008-3688 HAVP(HTTP Antivirus Proxy)是ClamAV杀毒扫描器的代理。 HAVP的sockethandler.cpp文件没有正确地处理客户端请求,如果客户端通过squid三明治模式的HAVP连接到没有响应的服务器的话,HAVP就会一直读取没有响应的服务器直到RECVTIMEOUT,通常为2分钟。之后HAVP会重新尝试一个循环,而由于未初始化的变量,这个循环为死循环。 仅在使用父代理且父代理为不需解析的数字IP地址时才会出现这个漏洞。 Christian Hilgers HAVP 0.88 Christian Hilgers ----------------- 目前厂商已经发布了升级补丁以修复这个安全问题,请到厂商的主页下载: <a href=http://www.server-side.de/download/havp-0.89.tar.gz target=_blank>http://www.server-side.de/download/havp-0.89.tar.gz</a>
