Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted jpg image file.\n\n### Patches\nThe bug is fixed in version v0.28.6.\n\n### References\nIssue: https://github.com/Exiv2/exiv2/issues/3333\nFixes: https://github.com/Exiv2/exiv2/pull/3335 (main branch), https://github.com/Exiv2/exiv2/pull/3345 (0.28.x branch)\n\n### For more information\nPlease see our [security policy](https://github.com/Exiv2/exiv2/security/policy) for information about Exiv2 security.\n\n## Affected packages\n\n- `exiv2 <= 0.17.3`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":14,"depthScoreParts":{"impact":13.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
