{"id":"CVE-2021-37616","state":"PUBLISHED","title":"Null pointer dereference in Exiv2::Internal::resolveLens0x8ff","description":"Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A null pointer dereference was found in Exiv2 versions v0.27.4 and earlier. The null pointer dereference is triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the interpreted (translated) data, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p t` or `-P t`). The bug is fixed in version v0.27.5.","publishedAt":"2021-08-09T00:00:00.000Z","updatedAt":"2024-08-04T01:23:01.227Z","severity":{"score":5.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["Exiv2 exiv2"],"affected":[{"vendor":"Exiv2","product":"exiv2","versions":[{"version":"<= 0.27.4","status":"affected"}]}],"references":["https://github.com/Exiv2/exiv2/security/advisories/GHSA-54f7-vvj7-545w","https://github.com/Exiv2/exiv2/pull/1758","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FMDT4PJB7P43WSOM3TRQIY3J33BAFVVE/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UYGDELIFFJWKUU7SO3QATCIXCZJERGAC/","https://security.gentoo.org/glsa/202312-06"],"weaknesses":["CWE-476"],"ingestedAt":"2026-10-29T19:48:47.122Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/37xxx/CVE-2021-37616.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-37616","state":"PUBLISHED","datePublished":"2021-08-09T00:00:00.000Z","dateUpdated":"2024-08-04T01:23:01.227Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2021-07-29T00:00:00.000Z"},"containers":{"cna":{"title":"Null pointer dereference in Exiv2::Internal::resolveLens0x8ff","descriptions":[{"lang":"en","value":"Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files.
