Several flaws were discovered in the JavaScript engine of Thunderbird. If a user had JavaScript enabled and were tricked into viewing malicious web content, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-0689, CVE-2009-2463, CVE-2009-3075)
Josh Soref discovered that the BinHex decoder used in Thunderbird contained a flaw. If a user were tricked into viewing malicious content, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-3072)

A security issue affects these releases of Ubuntu and its derivatives:
Several flaws were discovered in the JavaScript engine of Thunderbird. If a user had JavaScript enabled and were tricked into viewing malicious web content, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-0689, CVE-2009-2463, CVE-2009-3075)
Josh Soref discovered that the BinHex decoder used in Thunderbird contained a flaw. If a user were tricked into viewing malicious content, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-3072)
It was discovered that Thunderbird did not properly manage memory when using XUL tree elements. If a user were tricked into viewing malicious content, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-3077)
Jesse Ruderman and Sid Stamm discovered that Thunderbird did not properly display filenames containing right-to-left (RTL) override characters. If a user were tricked into opening a malicious file with a crafted filename, an attacker could exploit this to trick the user into opening a different file than the user expected. (CVE-2009-3376)
