{"id":"ALPINE-CVE-2025-26623","details":"Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A heap buffer overflow was found in Exiv2 versions v0.28.0 to v0.28.4. Versions prior to v0.28.0, such as v0.27.7, are **not** affected. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The heap overflow is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to gain code execution, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `fixiso`. The bug is fixed in version v0.28.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.","modified":"2026-11-03T06:32:51.174327749Z","published":"2025-02-18T20:15:33.153Z","upstream":["CVE-2025-26623"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2025-26623"}],"affected":[{"package":{"name":"exiv2","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.28.0"},{"fixed":"0.28.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-26623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.28.0"},{"fixed":"0.28.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-26623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.28.0"},{"fixed":"0.28.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-26623.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
