CVE-2014-3173
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe WebGL implementation in Google Chrome before 37.0.2062.94 does not ensure that clear calls interact properly with the state of a draw buffer, which allows remote attackers to cause a denial of service (read of uninitialized memory) via a crafted CANVAS element, related to gpu/command_buffer/service/framebuffer_manager.cc and gpu/command_buffer/service/gles2_cmd_decoder.cc.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe WebGL implementation in Google Chrome before 37.0.2062.94 does not properly validate draw buffer state when processing clear() operations. This allows a crafted CANVAS element to trigger reads of uninitialized memory from the GPU command buffer, resulting in information disclosure or denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Google Chrome versionNavigate to chrome://settings/help or look at 'About Google Chrome' in the menu to see the installed version numberAffected if The installed version is 37.0.2062.93 or earlier, or exactly matches any version from 37.0.2062.0 through 37.0.2062.10
-
Verify WebGL is enabledVisit chrome://flags/#enable-webgl and check the status of the 'WebGL' flag, or inspect if WebGL is available by navigating to a WebGL test pageAffected if WebGL is enabled (the vulnerability only applies when WebGL is active)
-
Confirm WebGL usage via canvas elementCheck browser history or logs for pages that render WebGL content using the CANVAS element with clear() operationsAffected if WebGL-rendered content has been processed through clear() calls on draw buffers
A user is affected if they run Chrome version 37.0.2062.93 or earlier (or versions 37.0.2062.0-10), have WebGL enabled, and have processed crafted WebGL canvas content with clear() operations.
