Apple Patch Summary

Apple released updates for all of its products. Noteworthy is the "Meltdown" patch for Siera (10.12) and El Capitan (10.11) only. Apple has released patches for this vulnerability for High Sierra (10.13) about a week ago. For iOS, CVE-2018-4100 fixes a vulnerability that was already abused in the wild as part of a DoS attack against iOS devices. As usual, the WebKit vulnerabilities are probably the most critical once as they can be exploited via Safari to execute arbitrary code. Full details from Apple can be found here. On ouir Slack channel, there was a report that the OS X patches may cause systems to fail if Carbon Black Response is installed. Please let us know if you are running this product and if you had issues.
