   Security Update 2017-003 (Yosemite and El Capitan)

   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 '[1]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 [2]10.10.5 Yosemite, 431.6 MB; for
   [3]10.11.6 El Capitan, 763.9 MB; [4]security content release notes)
