CVE-2011-0133: 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 access glyph data during layout actions for floating blocks associated with pseudo-elements, 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 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; …
