CVE-2015-1117: Apple iPhone OS

Medium severity, CVSS 6.9. EPSS: 0.4% chance of exploitation in the next 30 days.

The (1) setreuid and (2) setregid system-call implementations in the kernel in Apple iOS before 8.3, Apple OS X before 10.10.3, and Apple TV before 7.2 do not properly perform privilege drops, which makes it easier for attackers to execute code with unintended user or group privileges via a crafted app.

Affected products

• Apple iPhone OS: up to and including 8.2
• Apple Mac OS X: up to and including 10.10.2
• Apple tvOS: up to and including 7.1
