Libpng库未初始化指针数组内存破坏漏洞
Vulnerability Description
libpng是一个可对PNG图形文件实现创建、读写等操作的PNG参考库。 如果应用程序耗尽内存的话，libpng库在释放数组单元之前没有正确地初始化某些指针数组，这可能导致内存破坏。 在malloc包含有N个单元的数组时： for (i=0; ilt;N; i++) malloc element[i]; 如果应用程序在循环期间耗尽了内存的话，就不会初始化一些单元指针，之后Libpng会跳转到一个试图释放数组中所有单元(包括未初始化的区)的cleanup进程。 libpng库存在5种出现bug的情况。一种在
