  • thunderbird - mail/news client with RSS and integrated spam filter support
  • thunderbird-locales - Thunderbird Afrikaans language/region package

Details

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
handling downloadable fonts. The new OTS font sanitizing library was added
to mitigate these issues. (CVE-2010-3768)

The problem can be corrected by updating your system to the following package versions:

Ubuntu 10.04

After a standard system update you need to restart Thunderbird to make
all the necessary changes.
