Title

Mozilla Firefox和Mozilla Thunderbird输入验证错误漏洞

Description

Mozilla Firefox和Mozilla Thunderbird都是美国Mozilla基金会的产品。Mozilla Firefox是一款开源Web浏览器。Mozilla Thunderbird是一套从Mozilla Application Suite独立出来的电子邮件客户端软件。该软件支持IMAP、POP邮件协议以及HTML邮件格式。 Mozilla Firefox存在输入验证错误漏洞，该漏洞的存在是由于在实时范围分割期间降低寄存器分配时，对用户提供的输入验证不足。远程攻击者可利用该漏洞可以创建一个专门制作的网页，诱骗受害者访问它，在jit代码中触发注册混淆失败，并在系统上执行任意代码。该漏洞允许远程攻击者可利用该漏洞危及受影响的系统。
