{"id":"CVE-2021-32815","state":"PUBLISHED","title":"Denial of service due to assertion failure in crwimage_int.cpp","description":"Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The assertion failure is triggered when Exiv2 is used to modify 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 modifying 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 `fi`. ### Patches The bug is fixed in version v0.27.5. ### References Regression test and bug fix: #1739 ### For more information Please see our [security policy](https://github.com/Exiv2/exiv2/security/policy) for information about Exiv2 security.","publishedAt":"2021-08-09T00:00:00.000Z","updatedAt":"2024-11-19T14:12:57.892Z","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":"< 0.27.5","status":"affected"}]}],"references":["https://github.com/Exiv2/exiv2/security/advisories/GHSA-mv9g-fxh2-m49m","https://github.com/Exiv2/exiv2/pull/1739","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://lists.debian.org/debian-lts-announce/2023/01/msg00004.html","https://security.gentoo.org/glsa/202312-06"],"weaknesses":["CWE-617"],"ingestedAt":"2026-10-29T19:48:33.225Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/32xxx/CVE-2021-32815.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-32815","state":"PUBLISHED","datePublished":"2021-08-09T00:00:00.000Z","dateUpdated":"2024-11-19T14:12:57.892Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2021-05-12T00:00:00.000Z"},"containers":{"cna":{"title":"Denial of service due to assertion failure in crwimage_int.cpp","descriptions":[{"lang":"en","value":"Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files.
