漏洞描述
中文描述:

Expat是一款使用C语言编写的快速流式XML解析器。 Expat 2.0.1版本的libexpat模块中存在安全漏洞。当Expat在 Python,、PyXML、 w3c-libwww和其他软件中运行时，攻击者可以将包含UTF-8字符序列的特制XML文档作为libexpat模块中lib/xmltok_impl.c的updatePosition函数参数以触发buffer over-read，造成拒绝服务(应用程序崩溃)。

英文描述:

The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that trigger a buffer over-read, a different vulnerability than CVE-2009-2625.
