{"id":"JLSEC-2026-1307","details":"Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A null pointer dereference was found in Exiv2 versions v0.27.4 and earlier. The null pointer dereference is triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the interpreted (translated) data, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p t` or `-P t`). The bug is fixed in version v0.27.5.","modified":"2026-08-13T16:00:05.244450126Z","published":"2026-08-13T15:55:58.236Z","upstream":["CVE-2021-37616","EUVD-2021-24174"],"database_specific":{"sources":[{"modified":"2026-06-17T04:00:50.240Z","published":"2021-08-09T19:15:07.680Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2021-37616","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2021-37616","database_specific":{"status":"Modified"},"id":"CVE-2021-37616","imported":"2026-08-12T14:19:46.512Z"},{"id":"EUVD-2021-24174","imported":"2026-08-12T14:19:49.329Z","modified":"2024-08-04T01:23:01Z","published":"2021-08-09T00:00:00Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2021-24174","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2021-24174"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://github.com/Exiv2/exiv2/pull/1758"},{"type":"WEB","url":"https://github.com/Exiv2/exiv2/security/advisories/GHSA-54f7-vvj7-545w"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FMDT4PJB7P43WSOM3TRQIY3J33BAFVVE/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UYGDELIFFJWKUU7SO3QATCIXCZJERGAC/"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202312-06"}],"affected":[{"package":{"name":"Exiv2_jll","ecosystem":"Julia","purl":"pkg:julia/Exiv2_jll?uuid=d2dc9c37-b624-5257-85b1-2eb67ce3a11b"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1307.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V2","score":"AV:N/AC:M/Au:N/C:N/I:N/A:P"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
