Apple has released a security update to address two vulnerabilities that are being actively exploited. The Integer and buffer overflow vulnerabilities in WebKit allows an attacker to potentially trigger the vulnerability on the targeted device when the user visits a website with malicious exploit code created by the attacker. 

Successful exploitation of the vulnerabilities may lead to arbitrary code execution and compromise of the iOS device. Users are advised to enable automatic software update by going to Settings> General> Software Updates> Enable Automatic Updates or patch their products to the latest versions immediately.

For iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation)
