Apple fixed dozens of vulnerabilities in its software on Monday, including 60 vulnerabilities in its operating system, OS X, and 43 in its mobile operating system, iOS.
The OS X update graduates the desktop and server operating system to OS X El Capitan v10.11.6 and applies to anyone running OS X Mavericks v10.9.5, OS X Yosemite v10.10.5, or OS X El Capitan v10.11.
The updates mostly fix a number of glitches and bugs under the hood of the OS. As usual, the bulk of them apply to software libraries like OpenSSL, LibreSSL, and libxml2. Apple updated each library to their most recent versions to mitigate the issues.
Meanwhile 21 of the vulnerabilities could lead to arbitrary code execution, six with kernel privileges, and two that could go on and lead to the compromise of user information.
