Apple releases NTP security update for OS X users, addresses ‘critical security issue’


Apple released a security update on Monday for Mac users, addressing a “critical security issue” with the Network Time Protocol service on OS X Yosemite, Mavericks, and Mountain Lion. The update weighs in at 2.1MB, and you can find download links after the break. 

“This update addresses a critical security issue with the software that provides the Network Time Protocol service on OS X, and is recommended for all users,” Apple wrote on its support website.


As pointed out by MacRumors, the Monday update looks to address a problem originally discovered by the Google Security Team. The US Department of Homeland Security announced last Friday the security flaw gives a hacker the ability to execute arbitrary code using the privileges of the ntpd process.
