Description

Michal Zalewski reported two vulnerabilities, memory corruption when

adding news feed sources from a website (CVE-2008-1761) as well as when

processing HTML CANVAS elements to use scaled images (CVE-2008-1762).

Additionally, an unspecified weakness related to keyboard handling of

password inputs has been reported (CVE-2008-1764).
