Security Researcher Drops 15 Vulnerabilities for Windows and Adobe Reader 117

Posted by Soulskill from the go-big-or-go-home dept.
mask.of.sanity writes: Google Project Zero hacker Mateusz Jurczyk has dropped 15 remote code execution vulnerabilities, including a single devastating hack against Adobe Reader and Windows he reckons beats all exploit defenses. He said, "The extremely powerful primitive provided by the vulnerability, together with the fact that it affected all supported versions of both Adobe Reader and Microsoft Windows (32-bit) – thus making it possible to create an exploit chain leading to a full system compromise with just a single bug – makes it one of the most interesting security issues I have discovered so far." Jurczyk published a video demonstration of the exploit for 32-bit and 64-bit systems. His slides are here [PDF].

    Sorry, I am not clicking on a PDF link that demonstrates a PDF attack.

      Thank God I'm using Firefox. Had I accidentally clicked on that link, I'm sure I would have had a good 2 to 3 minutes to realize my mistake and to close the browser window, since that's just about how long it takes for Firefox's shitty builtin PDF.js PDF viewer to kick in and render even the smallest of PDFs.

                Pdf is a subset of PostScript, a turing complete programming language. It's most often used for rendering documents, but is in no way limited to that. You can program an emulator in ps and run Linux inside your pdf. Gif and jpeg are not executable code. They are just (compressed) color VALUES).

                There was one security hole in one specific executable LIBRARY which processes jpegs, but jpegs themselves are not executable and therefore essentially safe. Not so for pdf.

                It is hoped that pdf is slightly safer than pure PostScript, but it's not FUNDAMENTALLY safer.

      We installed Foxit Enterprise Reader and disabled in-browser PDF viewing for all browsers. This forces PDF downloads and everything displays wonderfully. It's lightning fast too!

      • I left Foxit behind when they started pushing crapware installs, and more critically, when it had some problems rendering some fairly basic PDFs correctly. Back to Adobe Reader for me as well.

        It's like that with MS Word docs as well. The damn things are so complicated that only the original code has a prayer of rendering it correctly, and even then not always.

    • The NSA is an offensive organization, not a defensive one. That's it's mission. There's a very good argument to make that it should be prioritizing defense over offense, especially given, say, the OPM EPIC hack, but that's not it's mission right now.

        That's according to you. Now according to the NSA their mission, from their Mission pagel:

        "The National Security Agency/Central Security Service (NSA/CSS) leads the U.S. Government in cryptology that encompasses both Signals Intelligence (SIGINT) and Information Assurance (IA) products and services, and enables Computer Network Operations (CNO) in order to gain a decision advantage for the Nation and our allies under all circumstances."

      They are, but when they find something, they add it to their arsenal and use it themselves instead of alerting anyone to the vulnerability. This fact was the subject of some hand-waving from the White House earlier in the year. There's a good chance NSA has known about several of these for a long time, which is a little disconcerting since the Adobe Type Manager exploit may date back to 1998.

    So, if I assume there's been at least one monthly major security issue attributable to Adobe (maybe twice monthly, once for Reader and once for Flash) ... and if we extend that over the last decade or, it becomes pretty obvious that Adobe writes some shitty code.

    I'm not sure a single software vendor on the planet, except Microsoft, has caused so much security holes in all of the history of computers.

    Pity we couldn't bill them for all the wasted time and resources.

    • To give them *some* credit, how many other pieces of software are as ubiquitous as Adobe Reader?

      • To give them *some* credit, how many other pieces of software are as ubiquitous as Adobe Reader?

        Well, there's Adobe Flash Player... which is the more wretched hive of scum and villainy?

    • Everybody writes shitty code. Not all code is as widely distributed as Adobe's.

  • Is there a good program that just *reads* without this constant useless updates and a 'need' for internet connection? Or should i just use an older version? Like 10 or 11?

  • I vote Adobe the worst software provider in terms of quality. We bash Microsoft quite a bit but think about it. Shockwave, Flash now Acrobat Reader must be the crappiest three pieces of software in terms of quality and vulnerabilities. I guess when you couple Adobe + Windows it's truly craptacular!
