How to Fix CVE-2024-24826

To remediate this vulnerability, upgrade all affected Exiv2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

exiv2 fixed: 0.16.1 
pip install exiv2>=0.16.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show exiv2

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-24826, inspect your installed packages using pip:

pip show exiv2

Analyze the terminal output to locate any version of Exiv2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.16.1), your application is affected.

Note: The pip show exiv2 command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. In Exiv2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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/Exiv2/exiv2/security/policy) for information about Exiv2 security. ### Credit This bug was found by [OSS-Fuzz](https://github.com/google/oss-fuzz).
