- 漏洞描述

Mozilla and Thunderbird contain a flaw that may lead to an unauthorized information disclosure. The issue is triggered when Mozilla or Thuderbird follow a link to an external CSS file. This will disclose the existence of a valid email address even if the victim is using the built-in feature which blocks external html from being loaded when displaying an email, resulting in a loss of confidentiality.
