Ben Hawkes, team leader at Google’s Project Zero security research group, revealed in a tweet that vulnerabilities identified as CVE-2019-7286 and CVE-2019-7287 in Apple’s iOS 12.1.4 security change log had been exploited in the wild as “zero day”.
A zero-day vulnerability refers to a security hole in software that is unknown to the software developer and the public, although it may already be known by attackers who are quietly exploiting it.
As ZDNet notes, it’s unclear under what circumstances the vulnerabilities were used, but one exploit involved the iOS Foundation component and a memory corruption issue that could allow an app to gain “elevated privileges” on an iPhone 5s and later, iPad Air and later, or iPod touch 6th generation. The second vulnerability potentially allowed for kernel privileges and affected the same devices.
CVE-2019-7286 and CVE-2019-7287 in the iOS advisory today (https://t.co/ZsIy8nxLvU) were exploited in the wild as 0day.

Apple credited “an anonymous researcher, Clement Lecigne of Google Threat Analysis Group, Ian Beer of Google Project Zero, and Samuel Groß of Google Project Zero” for discovering both vulnerabilities.
Apple’s iOS 12.1.4 update for the iPhone, iPad, and iPod touch, was principally designed to fix an insidious privacy-invading Group FaceTime bug discovered by a high school student that could be exploited to eavesdrop on conversations.
