Details
Several flaws were discovered in the Firefox 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 arbitrary code
with the privileges of the user invoking the program. (CVE-2009-2462,
CVE-2009-2463, CVE-2009-2464, CVE-2009-2465, CVE-2009-2466, CVE-2009-2469)
Attila Suszter discovered a flaw in the way Firefox processed Flash content.
If a user were tricked into viewing and navigating within a specially
crafted Flash object, a remote attacker could cause a denial of service or
possibly execute arbitrary code with the privileges of the user invoking
the program. (CVE-2009-2467)
It was discovered that Firefox did not properly handle some SVG content. An
attacker could exploit this to cause a denial of service or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2009-2469)
A flaw was discovered in the JavaScript engine. If a user were tricked into
viewing a malicious website, an attacker could exploit this perform
cross-site scripting attacks. (CVE-2009-2472)
