CVE-2018-13026
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 · uneditedAn issue was discovered in gpmf-parser 1.1.2. There is a heap-based buffer over-read in GPMF_parser.c in the function GPMF_Type.
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 heap-based buffer over-read vulnerability exists in gpmf-parser 1.1.2 within the GPMF_Type function in GPMF_parser.c. The function reads memory beyond the allocated heap buffer boundaries, potentially exposing sensitive data or causing a denial of service. This is a memory safety issue in C code where proper bounds checking is missing or incorrect.

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.
-
Locate the gpmf-parser library or source codeSearch for files named GPMF_parser.c, libgpmf, or gpmf-parser in your environment. Check installed system libraries, project dependencies, or source code directories.Affected if The gpmf-parser library or its source code is present in the environment
-
Identify the installed or compiled versionCheck for version strings in library binaries, version.h files, or source code headers. Look for version markers such as '1.1.2' or 'GPMF_PARSER_VERSION'. If using a package manager, run 'pkg-config --modversion gpmf-parser' or check installed package metadata.Affected if The version is exactly 1.1.2 or falls within the affected range (specifically 1.1.2)
-
Verify the vulnerable GPMF_Type function is in useSearch the codebase for calls to GPMF_Type, GPMF_Init, or GPMF_Parse functions. These indicate the parser is actively used. Check if media processing code imports or links against gpmf-parser.Affected if The application or service invokes the GPMF parser functions to process GPMF data
-
Confirm GPMF data processing from untrusted sourcesReview application logs or code to determine if the parser handles GPMF data from external sources such as user-uploaded videos, network streams, or file inputs that are not validated before parsing.Affected if The parser processes GPMF data from untrusted or user-controlled sources without prior validation
You are affected if gpmf-parser version 1.1.2 is present and your application uses the GPMF parser to process potentially untrusted GPMF data from media files.

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 a patched version of gpmf-parser that fixes the boundary check in GPMF_Type function. If no patch is available, implement input validation to ensure GPMF data sizes do not exceed allocated buffer sizes before calling the parser.
