Jesse Ruderman, Andreas Gal, Nils, Brian Hackett, and Igor Bukanov
discovered several memory issues in the browser engine. An attacker could
exploit these to crash THunderbird or possibly run arbitrary code as the
user invoking the program. (CVE-2010-3776, CVE-2010-3777, CVE-2010-3778)

Marc Schoenefeld and Christoph Diehl discovered several problems when
