Apple Releases OS X Yosemite 10.10.5 – Includes DYLD Vulnerability Patch

Apple on Thursday released OS X Yosemite 10.10.5, which includes bug fixes, a fix for the DYLD_PRINT_TO_FILE exploit, and performance enhancements.

The OS X 10.10.5 update, build 14F27, can be downloaded via the “Update” tab in the Mac App Store.

The update includes a fix for the DYLD_PRINT_TO_FILE exploit that could allow malware to gain root access to a Mac. The exploit is reported to be in the wild, so this is an important update for all Macs running Yosemite.

The update also:

• Improves compatibility with certain email servers when using Mail
• Fixes an issue in Photos that prevents importing videos from GoPro cameras
• Fixes an issue in QuickTime Player that prevented playback of Windows Media files.

This could be one of the last updates we’ll see for OS X Yosemite, as its successor, OS X 10.11 El Capitan, is scheduled for release to the public sometime in the fall.

Also released today was Security Update 2015-006 for Mavericks and Mountain Lion users, as well as Safari 8.0.8 for Yosemite, 7.1.8 for Mavericks, and 6.2.8 for Mountain Lion. (Thanks to MacRumors for that info.)
