Description
It was found that the Content Security Policy (CSP) implementation in
Thunderbird no longer blocked Thunderbird inline event handlers. Malicious
content could possibly bypass intended restrictions if that content relied
on CSP to protect against flaws such as cross-site scripting (XSS).
(CVE-2012-1944)
If a web server hosted content that is stored on a Microsoft Windows share,
or a Samba share, loading such content with Thunderbird could result in
Windows shortcut files (.lnk) in the same share also being loaded. An
attacker could use this flaw to view the contents of local files and
directories on the victim's system. This issue also affected users opening
content from Microsoft Windows shares, or Samba shares, that are mounted
on their systems. (CVE-2012-1945)
