漏洞描述
中文描述:

Apache HTTP Server是美国阿帕奇（Apache）软件基金会的一款开源网页服务器。该服务器具有快速、可靠且可通过简单的API进行扩充的特点。 Apache HTTP Server 2.2.17版本至2.2.21版本的mod_log_config模块中的mod_log_config.c文件中的log_cookie函数存在漏洞，该漏洞源于在使用单线程MPM时，未能正确处理%{}C格式字符串。远程攻击者可利用此漏洞借助同时缺乏name和value的cookie导致拒绝服务（守护进程崩溃）。

英文描述:

The log_cookie function in mod_log_config.c in the mod_log_config module in the Apache HTTP Server 2.2.17 through 2.2.21, when a threaded MPM is used, does not properly handle a %{}C format string, which allows remote attackers to cause a denial of service (daemon crash) via a cookie that lacks both a name and a value.
