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 2.0.x版本至2.0.64版本以及2.2.x版本至2.2.21版本中存在漏洞。由于server/util.c的ap_pregsub函数在启用mod_setenvif模块时不能限制环境变量值的大小，本地用户可通过带有特制SetEnvIf指示符的.htaccess文件导致拒绝服务（内存消耗或者空指针解引用）。
英文描述:
The ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, does not restrict the size of values of environment variables, which allows local users to cause a denial of service (memory consumption or NULL pointer dereference) via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, related to (1) the "len +=" statement and (2) the apr_pcalloc function call, a different vulnerability than CVE-2011-3607.
