{"id":"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.","aliases":["GHSA-57jj-75fm-9rq5"],"modified":"2026-05-15T12:04:19.635214546Z","published":"2021-04-19T19:15:18.017Z","related":["ALSA-2021:4173","openSUSE-SU-2024:12591-1"],"database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD","vendor_product":"debian:debian_linux","extracted_events":[{"last_affected":"10.0"}]},{"cpes":["cpe:2.3:o:fedoraproject:fedora:33:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:34:*:*:*:*:*:*:*"],"source":"CPE_FIELD","vendor_product":"fedoraproject:fedora","extracted_events":[{"last_affected":"33"},{"last_affected":"34"}]}]},"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2XQT5F5IINTDYDAFGVGQZ7PMMLG7I5ZZ/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/P2A5GMJEXQ5Q76JK6F6VKK5JYCLVFGKN/"},{"type":"ADVISORY","url":"https://github.com/Exiv2/exiv2/security/advisories/GHSA-57jj-75fm-9rq5"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2023/01/msg00004.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202312-06"},{"type":"FIX","url":"https://github.com/Exiv2/exiv2/pull/1536"},{"type":"EVIDENCE","url":"https://github.com/Exiv2/exiv2/issues/1530"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
