Georgi Guninski, Michal Zalewsk and Chris Evans discovered that the same-origin check in Thunderbird could be bypassed. If a user were tricked into opening a malicious website, an attacker could obtain private information from data stored in the images, or discover information about software on the user’s computer. (CVE-2008-5012)
Jesse Ruderman discovered that Thunderbird did not properly guard locks on non-native objects. If a user had JavaScript enabled and were tricked into opening malicious web content, an attacker could cause a browser crash and possibly execute arbitrary code with user privileges. (CVE-2008-5014)
