CVE-2009-2841: Apple Safari

Medium severity, CVSS 5.0. EPSS: 2.9% chance of exploitation in the next 30 days.

The HTMLMediaElement::loadResource function in html/HTMLMediaElement.cpp in WebCore in WebKit before r49480, as used in Apple Safari before 4.0.4 on Mac OS X, does not perform the expected callbacks for HTML 5 media elements that have external URLs for media resources, which allows remote attackers to trigger sub-resource requests to arbitrary web sites via a crafted HTML document, as demonstrated by an HTML e-mail message that uses a media element for X-Confirm-Reading-To functionality, aka rdar problem 7271202.

Affected products

• Apple Safari: up to and including 4.0.3; version 0.8 only; version 0.9 only; version 1.0 only; version 1.0.0 only; version 1.0.0b1 only; …
