{"id":"CVE-2021-29458","state":"PUBLISHED","title":"Out-of-bounds read in Exiv2::Internal::CrwMap::encode","description":"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.","publishedAt":"2021-04-19T00:00:00.000Z","updatedAt":"2024-08-03T22:02:51.987Z","severity":null,"assigner":"GitHub_M","products":["Exiv2 exiv2"],"affected":[{"vendor":"Exiv2","product":"exiv2","versions":[{"version":"< 0.27.4","status":"affected"}]}],"references":["https://github.com/Exiv2/exiv2/issues/1530","https://github.com/Exiv2/exiv2/security/advisories/GHSA-57jj-75fm-9rq5","https://github.com/Exiv2/exiv2/pull/1536","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2XQT5F5IINTDYDAFGVGQZ7PMMLG7I5ZZ/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/P2A5GMJEXQ5Q76JK6F6VKK5JYCLVFGKN/","https://lists.debian.org/debian-lts-announce/2023/01/msg00004.html","https://security.gentoo.org/glsa/202312-06"],"weaknesses":["CWE-125"],"ingestedAt":"2026-10-29T19:48:21.578Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/29xxx/CVE-2021-29458.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-29458","state":"PUBLISHED","datePublished":"2021-04-19T00:00:00.000Z","dateUpdated":"2024-08-03T22:02:51.987Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2021-03-30T00:00:00.000Z"},"containers":{"cna":{"title":"Out-of-bounds read in Exiv2::Internal::CrwMap::encode","descriptions":[{"lang":"en","value":"Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files.
