CVE-2016-1728: Apple iPhone OS

Medium severity, CVSS 4.3. EPSS: 1.7% chance of exploitation in the next 30 days.

The Cascading Style Sheets (CSS) implementation in Apple iOS before 9.2.1 and Safari before 9.0.3 mishandles the "a:visited button" selector during height processing, which makes it easier for remote attackers to obtain sensitive browser-history information via a crafted web site.

Affected products

• Apple iPhone OS: up to and including 9.2
• Apple Safari: up to and including 9.0.2
