CVE-2011-4688: Mozilla Firefox

Medium severity, CVSS 5.0. EPSS: 1.8% chance of exploitation in the next 30 days.

Mozilla Firefox 8.0.1 and earlier does not prevent capture of data about the times of Same Origin Policy violations during IFRAME loading attempts, which makes it easier for remote attackers to determine whether a document exists in the browser cache via crafted JavaScript code.

Affected products
