glibc 是为系统上多个程序所用的一个标准函数库。 在 glibc 函数库中的一个 DNS 用来解析网络名和网络地址的解析器被发现存在一个缓冲溢出缺陷(CAN-2002-0684)。glibc 2.2.5 及更早版本都受此影响。如果系统在 /etc/nsswitch.conf 文件中的"networks"数据库带有"dns"设置，将会受此影响，但是 Hat Linux 缺省设置是将"networks" 设置为"files" ，所以不受此影响。 存在的第二个问题是 glibc 2.0.x 的为应用程序之间的实现提供了兼容性 glibc-compat 数据包的一个bug(CAN-2002-0651)，不过是仅仅使得Red Hat Linux 5.0, 5.1, 和 5.2 的应用程序的实现受到影响。 受影响系统： Red Hat Linux 6.2 - alpha, i386, i686, sparc, sparcv9 Red Hat Linux 7.0 - alpha, alphaev6, i386, i686 Red Hat Linux 7.1 - alpha, alphaev6, i386, i686, ia64 Red Hat Linux 7.2 - i386, i686, ia64 Red Hat Linux 7.3 - i386, i686 攻击方法： 暂无有效攻击代码 解决方案： 安装更新软件包： rpm -Fvh
代表你要用来更新的 RPMs。只有目前有安装的 RPMs 才可更新，那些没有安装过但是包含在 filenames 内的 RPMs 将不会被更新。注意，如果你目前所在目录下只包含想要的RPMs，你也可以使用万用字符(*.rpm)请注意，你也可以由Red Hat Network 取得 更新，有各种更新的方式，要使用 Red Hat Network，可由以下指令激活 Red Hat Update Agent: up2date 这将激活一个互动的程序将您系统上适当的RPMs升级。 在取得更新之前，确定所有之前所有跟你系统相关的错误修正都已取得要对你特定系统架构进行更新： rpm -Fvh
