Vulnerability Title
Opera Web RLE远程拒绝服务漏洞
Vulnerability Description
Opera是挪威欧朋（Opera Software）公司所开发的一款Web浏览器，它支持多窗口浏览、可定制用户界面等。 Opera在处理畸形的BMP文件时存在漏洞，可能导致系统一定时间的性能大幅下降。 BMP文件允许游程长度编码4位和8位的位图。BMP格式中所使用的RLE有一些额外的功能，如移动到其他行和列的写指针(00 02 XX YY)。Opera实现00 02 XX YY功能的算法过于缓慢，正常解压算法是将XX和YY * width添加到写指针，而Opera的实现要执行XX + YY * width
