CVE-2016-1924
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 opj_tgt_reset function in OpenJpeg 2016.1.18 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted JPEG 2000 image.
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 · moderate confidenceThe opj_tgt_reset function in OpenJpeg 2016.1.18 contains an out-of-bounds read vulnerability triggered when parsing crafted JPEG 2000 images. The function fails to properly validate bounds before reading memory, causing the application to read beyond allocated buffers and crash.

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.
-
Identify OpenJpeg installation and versionRun 'dpkg -l | grep openjpeg' on Debian-based systems, or 'rpm -qa | grep openjpeg' on RHEL-based systems, or check for libopenjp* files in /usr/lib/Affected if OpenJpeg is installed and version is 2.1.0 or lower
-
Locate OpenJpeg library filesSearch for shared library files: 'find /usr -name "libopenjp*" 2>/dev/null' and note the version in the filename if presentAffected if OpenJpeg library files exist with version 2.1.0 or earlier in the filename
-
Identify applications using OpenJpegRun 'ldd <application_binary> | grep openjp' to check if any deployed applications are linked against OpenJpeg, or check application documentation for JPEG 2000 supportAffected if Applications that process JPEG 2000 images are linked to a vulnerable OpenJpeg version
-
Assess JPEG 2000 processing exposureReview log files, web uploads, or document processing workflows that handle .jp2, .j2k, .jpx or .jpf files which use OpenJpeg for decodingAffected if The environment processes untrusted or user-submitted JPEG 2000 files using a vulnerable OpenJpeg library
The environment is affected if OpenJpeg version 2.1.0 or lower is installed AND applications process JPEG 2000 files from untrusted sources.

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 to the latest OpenJpeg version that includes the patch for this vulnerability, or implement proper bounds checking in the opj_tgt_reset function before processing target marker data in JPEG 2000 files.
