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版本中存在缓冲区错误漏洞。该漏洞源于libexpat的lib/xmltok.c包含big2_toUtf8函数,例如Perl中的XML-Twig module使用的函数,XML文件中的一个畸形的UTF-8序列可以引发缓冲器通读，攻击者可以通过该数列引起拒绝服务(应用程序攻击)。

英文描述:

The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module for Perl, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with malformed UTF-8 sequences that trigger a buffer over-read, related to the doProlog function in lib/xmlparse.c, a different vulnerability than CVE-2009-2625 and CVE-2009-3720.
