The H reports on some 40-60 Adobe PDF reader holes found by Google employees—not all of which were fixed in the August 14 update. In fact, none of them were fixed for Linux as no release was made for Linux. "Google employees Mateusz Jurczyk and Gynvael Coldwind initially examined the PDF engine of the Chrome browser and discovered numerous holes. They then tested Adobe Reader and found about 60 issues that triggered crashes, 40 of which are potential attack vectors. When the two researchers reported their discoveries to Adobe, the company promised to provide fixes – but also indicated that not all the holes would be closed on Patch Day in August."
