CVE-2015-1227
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 DragImage::create function in platform/DragImage.cpp in Blink, as used in Google Chrome before 41.0.2272.76, does not initialize memory for image drawing, which allows remote attackers to have an unspecified impact by triggering a failed image decoding, as demonstrated by an image for which the default orientation cannot be used.
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 confidenceA memory initialization vulnerability exists in Blink's DragImage::create function where uninitialized memory is used when drawing images. When an image fails to decode (specifically images where default orientation cannot be determined), the memory allocated for image drawing is not properly initialized, potentially allowing disclosure of sensitive memory contents to remote attackers.

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 version numberOpen Chrome and navigate to chrome://settings/help, or run 'google-chrome --version' from the command line, or click 'About Google Chrome' from the Help menuAffected if The installed version is 40.0.2214.115 or any version lower than 40.0.2214.115
-
Confirm Chrome is running a stable channel buildIn chrome://settings, under 'About Chrome', verify the update status. Stable channel versions are listed without any channel designation (e.g., '40.0.2214.115' without 'beta' or 'dev')Affected if The browser is on stable channel and version is at or below 40.0.2214.115
-
Verify drag operations with images have occurredThe vulnerability triggers in the DragImage::create function when dragging images from web pages. Check browser history or consider if the user has dragged images from websitesAffected if The browser has been used to drag images from web pages and the version is affected
A user is affected if their Google Chrome version is 40.0.2214.115 or lower on the stable channel and they have performed drag operations with images from web pages.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Google Chrome to version 41.0.2272.76 or later. For other applications using the Blink rendering engine, apply the vendor patch that initializes memory in the DragImage::create function before image drawing operations.
