{"schemaVersion":3,"id":"CVE-2021-29473","aliases":["UBUNTU-CVE-2021-29473","DEBIAN-CVE-2021-29473"],"status":"published","duplicateOf":null,"title":null,"description":"Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. An out-of-bounds read was found in Exiv2 versions v0.27.3 and earlier. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. 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. Please see our security policy for information about Exiv2 security.","dates":{"published":"2021-04-26T00:00:00.000Z","modified":"2024-08-03T22:11:05.516Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":2.6,"severity":"low","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:H/Au:N/C:N/I:N/A:P","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":2.5,"severity":"low","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
