   Security Update 2016-004 (Mavericks and Yosemite)

   Agen G. N. Schmitz

   Apple has released [1]Security Update 2016-004 for OS X 10.9 Mavericks
   and 10.10 Yosemite, which brings a few select patches from the 10.11.5
   El Capitan release (see '[2]Apple Releases OS X 10.11.6, iOS 9.3.3,
   tvOS 9.2.2, and watchOS 2.2.2,' 18 July 2016) to the two older
   operating systems. The update resolves multiple memory corruption
   issues in CoreGraphics, ImageIO, and libxml2, which could allow a
   remote attacker to execute arbitrary code. (Free. For [3]10.9.5
   Mavericks, 371.2 MB; for [4]10.10.5 Yosemite, 456 MB)
