xpdf StreamPredictor堆溢出漏洞
Vulnerability Description
Xpdf是便携文档格式(PDF)文件的开放源码浏览器。 多家厂商软件版本所捆绑的xpdf中存在堆溢出漏洞。Predictor流解析代码没有充分的验证输入。xpdf/Stream.cc的StreamPredictor::StreamPredictor函数从PDF文件中用户可控值读取numComps的值，然后在StreamPredictor函数中使用该值用于一系列的计算。攻击者可以使用特制的值强迫gmalloc调用分配最少的字节数，然后PDF文件的用户数据就可以覆盖所分配的内存位置，破坏堆内存。成功利用这个漏
