patches.

Description :

It was discovered that QtWebKit did not properly handle certain

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 attacker could cause a denial of service or possibly execute
