python buffer overflow

Stack-based buffer overflow in Python 2.4.2 and earlier, running on Linux 2.6.12.5 under gcc 4.0.3 with libc 2.3.5, allows local users to cause a "stack overflow," and possibly gain privileges, by running a script from a current working directory that has a long name, related to the realpath...

SuSe mount/umount溢出漏洞

由于mount/umount命令没有对用户的输入进行正确的边界检查，如果攻击者以超长的相对路径名为参数运行mount/umount程序，将会覆盖为realpath函数动态分配的内存空间的内容。攻击者通过修改堆heap数据有可能会获得root特权。 SuSe Linux 所有版本 Package: util 2.10f 升级util软件包，或去掉mount/umount的suid位。 ftp://ftp.suse.com/pub/suse/axp/update/6.1/a1/util-2.10f-4.alpha.rpm...

PHP realpath()函数绕过safe_mode及open_basedir安全限制漏洞

PHP是一种流行的WEB服务器端编程语言。 PHP的realpath函数实现上存在漏洞，远程攻击者可能利用此漏洞绕过某些安全限制。 PHP的fileexists函数不允许检查是否存在openbasedir指定目录之外的文件，但readfile没有这个限制，允许检查文件系统的任意位置是否存在某一文件。如果realpath$filename返回了字符串（也就是非false），就表示文件存在，这就导致绕过了openbasedir限制。 PHP PHP 5.2.3 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： http://www.php.net/downloads.php...
