CVE-2016-1702
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 SkRegion::readFromMemory function in core/SkRegion.cpp in Skia, as used in Google Chrome before 51.0.2704.79, does not validate the interval count, which allows remote attackers to cause a denial of service (out-of-bounds read) via crafted serialized data.
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 SkRegion::readFromMemory function in Skia does not validate the interval count from serialized data before processing, allowing an attacker to trigger an out-of-bounds read by providing crafted data with a malformed interval count.

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 run 'google-chrome --version' in terminalAffected if Version is 51.0.2704.63 or lower
-
Check Skia library version on Debian/UbuntuRun 'dpkg -l | grep skia' or 'apt show libskia-dev' to list installed Skia packagesAffected if Skia library version from the affected Ubuntu (14.04, 15.10, 16.04) or Debian 8.0 distributions is installed and matches the vulnerable version range
-
Check Skia library version on RHELRun 'rpm -qa | grep -i skia' to list installed Skia packagesAffected if Skia library from RHEL 6.0 Desktop, Server, or Workstation is installed and matches the vulnerable version
-
Check Skia library version on openSUSERun 'rpm -qa | grep -i skia' or check installed packages via YaSTAffected if Skia library from openSUSE Leap 42.1 or openSUSE 13.2 is installed and matches the vulnerable version
-
Identify applications using Skia for region deserializationReview any custom or third-party applications that process untrusted serialized SkRegion data through Skia's readFromMemory functionAffected if Any application processes serialized SkRegion data from untrusted sources without additional validation
You are affected if Chrome version is 51.0.2704.63 or lower, or if a Skia library from any of the affected Ubuntu, Debian, RHEL 6.0, or openSUSE versions is installed and processes untrusted serialized region data.

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 51.0.2704.79 or later, or update the Skia library to a version containing the interval count validation fix.
