发布日期:2007-05-29 更新日期:2007-08-28受影响系统:
Apache Group Apache 2.2.4

Apache Group Apache 1.3.37
描述:
BUGTRAQ ID: 24215
CVE(CAN) ID: CVE-2007-3304
Apache HTTP Server是一款流行的Web服务器。
Apache HTTP Server Worker进程实现上存在多个漏洞,本地攻击者可能利用这些漏洞导致服务不可用。
在发送信号之前Apache HTTP Server没有验证进程为Apache子进程。能够在Apache HTTP Server上运行脚本的本地攻击者可以控制记分板并终止任意进程,导致拒绝服务。
如果Apache httpd安装了Prefork MPM模块的话,本地攻击者就可以修改worker_score和process_score数组使其引用任意进程ID,主进程向其发送了SIGUSR1信号的话就会导致拒绝服务。
