As part of today's product announcements, Apple released new operating systems across its different products. In addition to new features, these updates do address a number of security issues as well.
OS X Server 5.1 ( for Yosemite 10.10.5 )
This update improves warnings in case the administrator stores backups insecurely and removes old SSL ciphers (RC4). Also, authentication bypass issues are addressed in the Wiki.
The Safari update is available for OS X back to 10.9 (Mavericks). It fixes a total of 12 vulnerabilities, some can be used to execute arbitrary code.
OS X El Capitan 10.11.4 (Security Update 2016-002)
A total of 59 vulnerabilities are patched (I hope I counted them right). Here are some of the highlights:
Apple USB Networking (CVE-2016-1734): This vulnerability could lead to arbitrary code execution if a malicious USB devices is connected to the computer.
Bluetooth (CVE-2016-1735/1736): Bluetooth can be used to execute arbitrary code. It isn't clear (but likely) that you first need to pair with the device which would mitigate the problem somewhat.
Messages (CVE-2016-1788): This vulnerability, which would allow the interception of iMessage messages has gotten a lot of press in the last couple days.
OpenSSH (CVE-2016-0777,0778): The roaming vulnerablity that could lead to a leak of the private key is fixed in this patch.
Wi-Fi (CVE-2016-0801/0802): A malicious WiFi frame could be used to execute arbitrary code. Since this requires an unspecified ether type, I am assuming that this requires that the victim first associates with the network. But the advisory doesn't provide sufficient details to tell for sure.
Two vulnerabilities. One in otool (a tool to display object files) and another two vulnerabilities in subversion.
A lot of overlap here with the OS X and Safari patches. Note that the Watch is also vulnerable to the WiFi exploits, but not the Bluetooth issues.
A total of 36 vulnerabilities, many of which are also patched for OS X. The Wifi vulnerability applies to iOS just as for the WatchOS and OS X.
Again a lot of overlap with the other updates.
In short: patch...
