Security Update 2017-003 (Yosemite and El Capitan)
By Agen G. N. Schmitz
Apple has released Security Update 2017-003 for OS X 10.10 Yosemite and 10.11 El Capitan, patching security vulnerabilities that the company also addressed in macOS 10.12.6 Sierra (see “Apple Releases macOS 10.12.6, iOS 10.3.3, watchOS 3.2.3, and tvOS 10.2.2,” 19 July 2017). Recommended for all users, the security update addresses a variety of memory corruption issues that affected kernel and system privileges and could lead to arbitrary code execution. It also improves bounds checking to prevent a maliciously crafted XML document from disclosing user information. (Free. For 10.10.5 Yosemite, 431.6 MB; for 10.11.6 El Capitan, 763.9 MB; security content release notes)
