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 · unedited
Multiple integer overflows in OpenJPEG, as used in PDFium in Google Chrome before 53.0.2785.89 on Windows and OS X and before 53.0.2785.92 on Linux, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted JPEG 2000 data that is mishandled during opj_aligned_malloc calls in dwt.c and t1.c.

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 confidence

Integer overflows in OpenJPEG's opj_aligned_malloc function in dwt.c and t1.c allow heap-based buffer overflows when processing crafted JPEG 2000 data, as used in PDFium within Google Chrome.

MitigationUpdate Google Chrome to version 53.0.2785.89 or later on Windows/OS X, or 53.0.2785.92 or later on Linux to patch the vulnerable OpenJPEG library.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Google Chrome version on Windows, macOS, or Linux
    Open chrome://version in the Chrome address bar or go to Help > About Google Chrome. Note the version number shown (e.g., 52.0.2743.116)
    Affected if The displayed version is 52.0.2743.116 or any earlier version (e.g., 51.x, 50.x, etc.)
  2. Check OpenJPEG library version on OpenSUSE Leap 42.1
    Run 'rpm -qa | grep -i openjpeg' or 'zypper se openjpeg' in terminal to list installed OpenJPEG packages, then run 'rpm -q <package-name>' to get the exact version
    Affected if OpenJPEG is installed from the default repositories on OpenSUSE Leap 42.1, as any version on this specific OS release is affected according to the advisory

You are affected if you are running Google Chrome version 52.0.2743.116 or earlier, or if you have OpenJPEG installed on OpenSUSE Leap 42.1.
