漏洞描述
中文描述:

Libxml2是GNOME项目组所研发的一个基于C语言的用来解析XML文档的函数库，它支持多种编码格式、Xpath解析、Well-formed和valid验证等。 libxml2 2.9.2之前版本的parser.c脚本中存在安全漏洞，该漏洞源于程序禁用实体替换时，没有正确处理实体扩展。攻击者可借助带有大量嵌套实体引用的XML文档利用该漏洞造成拒绝服务（CPU消耗）。

英文描述:

parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML document containing a large number of nested entity references, a variant of the "billion laughs" attack.
