   Security Update 2017-002 (Yosemite and El Capitan)

   Agen G. N. Schmitz

   Apple has released Security Update 2017-002 for OS X 10.10 Yosemite and
   10.11 El Capitan, patching a number of vulnerabilities that were also
   included in the macOS 10.12.5 Sierra release (see "[1]Apple Releases
   macOS 10.12.5, iOS 10.3.2, watchOS 3.2.2, and tvOS 10.2.1," 15 May
   2017). For both El Capitan and Yosemite, the security update addresses
   a memory consumption issue that could lead to arbitrary code execution,
   fixes validation issues that could allow an application to read
   restricted memory, and resolves a memory corruption issue that could
   allow an application to escape its sandbox. (Free. For [2]10.10.5
   Yosemite, 421.1 MB; for [3]10.11.6 El Capitan, 710.6 MB; [4]security
