安全漏洞
Apple Safari多个拒绝服务及欺骗漏洞

发布日期:2008-04-22
更新日期:2008-04-23

受影响系统:
Apple Safari 3.1.1
描述:
BUGTRAQ  ID: 28891
CVE(CAN) ID: CVE-2008-1999,CVE-2008-2001

Safari是苹果家族操作系统默认所捆绑的WEB浏览器。

Safari在处理畸形恶意的JavaScript时存在漏洞,用户访问包含有恶意代码的网页时会导致浏览器崩溃。

在通过document.write写入到同一页面时,无限的while循环可能导致Safari出现以下错误崩溃:

Access violation when writing to [0FDFFFEE]

如果使用safari打开了file://类链接的话,浏览器可能出现以下错误崩溃:

Access violation when reading [00000004]

如果使用safari跟随了A@domain.com类链接的话,在试图连接到@后的域时可能会误导浏览器定向,这有助于攻击者执行网络钓鱼攻击。
