Title
PHP 'gdImageRotateInterpolated'函数拒绝服务漏洞
Description
PHP(PHP:Hypertext Preprocessor,PHP:超文本预处理器)是PHP Group和开放源代码社区共同维护的一种开源的通用计算机脚本语言。该语言支持多重语法、支持多数据库及操作系统和支持C、C++进行程序扩展等。 PHP的ext/gd/libgd/gd_interpolation.c文件中的'gdImageRotateInterpolated'函数存在安全漏洞。由于'imagerotate'函数未能充分过滤较大的'bgd_color'参数。远程攻击者可利用该漏洞获取敏感信息,或造成拒绝服务(越边界读取和应用程序崩溃)。
