CVE-2011-0149: Apple iTunes

High severity, CVSS 7.6. EPSS: 3.2% chance of exploitation in the next 30 days.

WebKit, as used in Apple iTunes before 10.2 on Windows, does not properly parse HTML elements associated with document namespaces, which allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via vectors related to a "dangling pointer" and iTunes Store browsing, a different vulnerability than other CVEs listed in APPLE-SA-2011-03-02-1.

Affected products

• Apple iTunes: up to and including 10.1.2; version 4.0.0 only; version 4.0.1 only; version 4.1.0 only; version 4.2.0 only; version 4.5 only; …
