{"id":"ALPINE-CVE-2021-29458","details":"Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An out-of-bounds read was found in Exiv2 versions v0.27.3 and earlier. The out-of-bounds read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, 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 insert. The bug is fixed in version v0.27.4.","modified":"2026-11-03T06:32:39.076687721Z","published":"2021-04-19T19:15:18.017Z","upstream":["CVE-2021-29458"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-29458"}],"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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-29458.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:N/I:N/A:H"}]}
