Apple fixes 0-Day Vulnerability in Older Operating Systems
This update fixes the ImageIO vulnerability Apple patched for current operating systems last week. Now, Apple follows up with a patch for its older, but still supported, operating system versions.
According to Citizen Lab, this vulnerability is already being exploited. Exploitation took advantage of the ImageIO vulnerability and a vulnerability in the Apple wallet "PassKit" API to send a "Pass" to the victim, including the malicious image. These older operating systems support PassKit, but it needs to be clarified if they are vulnerable to the PassKit issue.
