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.","severity":{"version":"3.1","score":3.3,"vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","level":"low","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.01119,"percentile":0.66377,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-125"],"published":"2021-04-30T00:00:00Z","modified":"2026-11-03T06:32:38Z","fixes":[{"ecosystem":"Alpine:v3.13","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.14","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.15","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.16","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.17","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.18","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.19","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.20","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.21","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.22","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"exiv2","fixed_in":["0.27.3-r2"],"sources":["osv"]},{"ecosystem":"Azure
