Description

Impact

An out-of-bounds read was found in Exiv2 version v0.28.1. The vulnerable function, QuickTimeVideo::NikonTagsDecoder, was new in v0.28.0 (see https://github.com/Exiv2/exiv2/pull/2337), so Exiv2 versions before v0.28 are not affected. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The out-of-bounds read is triggered when Exiv2 is used to read the metadata of a crafted video file.

Patches

The bug is fixed in version v0.28.2.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for exiv2, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update exiv2 to 0.16.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g9xm-7538-mq8w is resolved across your whole dependency graph.

  3. Workarounds

    Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.

Frequently Asked Questions

### Impact An out-of-bounds read was found in Exiv2 version v0.28.1. The vulnerable function, `QuickTimeVideo::NikonTagsDecoder`, was new in v0.28.0 (see https://github.com/Exiv2/exiv2/pull/2337), so Exiv2 versions before v0.28 are _not_ affected. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The out-of-bounds read is triggered when Exiv2 is used to read the metadata of a crafted video file. ### Patches The bug is fixed in version v0.28.2. ### For more information Please see our [security policy](https://github.com/
