data structures. If a user were tricked into viewing a malicious website,
an attacker could exploit this to execute arbitrary code with the
privileges of the user invoking the program. (CVE-2009-0945)

Several flaws were discovered in the QtWebKit browser and JavaScript
engines. If a user were tricked into viewing a malicious website, a remote

with the privileges of the user invoking the program. (CVE-2009-1687,

files from different security zones. (CVE-2009-1699, CVE-2009-1713)
