PHP GD扩展释放资源访问代码执行漏洞

PHP是一款广泛使用的WEB开发脚本语言。 PHP GD扩展存在设计错误，远程攻击者可能利用此漏洞获得对释放内存的访问并使用恶意数据覆盖而执行任意代码。 问题存在于GD函数中，在通过资源识别器获得资源数据后，可能用usercode来中断PHP函数，usercode就会会破坏资源，并获取与其内存相同位置来分配PHP字符串相同大小的空间作为释放资源。这个字符串可以用于建立特定构建的资源，以允许利用内部PHP函数，当恶意中断终止函数时，会继续使用替代资源数据。导致任意代码执行。 要获得需要的函数中断，通常需要放置对象到函数的某个参数中，这会在转化一个超长值时触发PHP错误。 PHP PHP...
