According to Microsoft, the build instigated a cache of compressed 'pages,' or contiguous memory blocks, that were stored in virtual memory rather than written to the device's physical memory or disk drive. Several on Reddit wondered whether the changes in build 10525 to Windows 10's memory management were behind the Chrome snafu. Alternately, users can switch to 32-bit Chrome, or another browser. That, of course, also disables one of Chrome's most important defenses. and Israeli coders to sabotage Iran's nuclear fuel enrichment facilities, made extensive use of ROP.Īccording to users on Reddit, the 64-bit version can be forced to run by appending '-no-sandbox' (without the quotation marks) to the Windows shortcut for Chrome. ROP has a rich history: The Stuxnet worm, reportedly created by U.S. ROP, for 'return-oriented programming,' is an exploit technique that has been a past focus of Microsoft's defensive efforts. Schuh also linked to an associated entry in the bug tracker, which referred to requests by both Microsoft and Intel to Google to change Chrome 'to work better with their ongoing ROP mitigation efforts.' Schuh's reference to 'e10s' was to Mozilla's work on a sandboxing technology for its Firefox browser. 'If Firefox e10s is also breaking as well, then it must be something pretty basic, like our hooks breaking under CFG.'Ĭhrome relies on an anti-exploitation technology, colloquially called a 'sandbox,' to isolate the browser's processes as part of an effort to stop or at least impede attackers leveraging a vulnerability, hopefully blocking them from planting malware on a device. 'Cutting through the noise, it looks like the sandbox is breaking in the Win10 10525 previews for 64-bit Chrome,' acknowledged Justin Schuh, a Google software engineer, in one message on the bug tracker. The 32-bit browser, however, works fine.Īn entry in the Chromium bug tracker - Chromium is the open-source project that feeds code into Chrome - was logged yesterday. 'I tried reinstalling Chrome, I even tried installing a different branch (the beta one), but I just cannot get it to work,' added James1o1o.Īccording to the reports, and confirmed by Computerworld, the 64-bit version of Chrome, which made it to the Stable channel a year ago, does not run on Windows 10 build 10525. A much longer thread on Reddit also tackled the problem.
