{"id":"ALPINE-CVE-2021-29623","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 read of uninitialized memory was found in Exiv2 versions v0.27.3 and earlier. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The read of uninitialized memory is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to leak a few bytes of stack memory, if they can trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.4.","modified":"2026-11-03T06:32:39.180378196Z","published":"2021-05-13T17:15:07.440Z","upstream":["CVE-2021-29623"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-29623"}],"affected":[{"package":{"name":"exiv2","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}},{"package":{"name":"exiv2","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/exiv2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29623.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"}]}
