{"id":"UBUNTU-CVE-2021-37615","details":"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.","modified":"2026-04-22T14:52:29.408717Z","published":"2021-08-09T20:15:00Z","related":["USN-5043-1"],"upstream":["CVE-2021-37615"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-37615"},{"type":"REPORT","url":"https://github.com/Exiv2/exiv2/pull/1758"},{"type":"REPORT","url":"https://github.com/Exiv2/exiv2/security/advisories/GHSA-h9x9-4f77-336w"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5043-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2021-37615"}],"affected":[{"package":{"name":"exiv2","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/exiv2@0.27.2-8ubuntu2.6?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.2-8ubuntu2.6"}]}],"versions":["0.25-4ubuntu2","0.25-4ubuntu3","0.27.2-8ubuntu2","0.27.2-8ubuntu2.2","0.27.2-8ubuntu2.4","0.27.2-8ubuntu2.5"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"exiv2","binary_version":"0.27.2-8ubuntu2.6"},{"binary_name":"libexiv2-27","binary_version":"0.27.2-8ubuntu2.6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-37615.json"}},{"package":{"name":"exiv2","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/exiv2@0.27.3-3ubuntu4?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.3-3ubuntu4"}]}],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"exiv2","binary_version":"0.27.3-3ubuntu4"},{"binary_version":"0.27.3-3ubuntu4","binary_name":"libexiv2-27"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-37615.json"}}],"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"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
