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."}],"affected":[{"vendor":"Exiv2","product":"exiv2","versions":[{"version":"< 0.27.4","status":"affected"}]}],"references":[{"url":"https://github.com/Exiv2/exiv2/security/advisories/GHSA-5p8g-9xf3-gfrr"},{"url":"https://github.com/Exiv2/exiv2/commit/783b3a6ff15ed6f82a8f8e6c8a6f3b84a9b04d4b"},{"name":"FEDORA-2021-0b27f220bd","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NDMZTVQAZSMLPTDVDYLBHAAF7I5QXVYQ/"},{"name":"FEDORA-2021-dde4d7d47e","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/K3HKXR6JOVKMBE4HY4FDXNVZGNCQG6T3/"},{"name":"GLSA-202312-06","tags":["vendor-advisory"],"url":"https://security.gentoo.org/glsa/202312-06"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE","baseScore":3.3,"baseSeverity":"LOW"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-125 Out-of-bounds Read","cweId":"CWE-125"}]}],"source":{"advisory":"GHSA-5p8g-9xf3-gfrr","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T22:02:51.889Z"},"title":"CVE Program Container","references":[{"url":"https://github.com/Exiv2/exiv2/security/advisories/GHSA-5p8g-9xf3-gfrr","tags":["x_transferred"]},{"url":"https://github.com/Exiv2/exiv2/commit/783b3a6ff15ed6f82a8f8e6c8a6f3b84a9b04d4b","tags":["x_transferred"]},{"name":"FEDORA-2021-0b27f220bd","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NDMZTVQAZSMLPTDVDYLBHAAF7I5QXVYQ/"},{"name":"FEDORA-2021-dde4d7d47e","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/K3HKXR6JOVKMBE4HY4FDXNVZGNCQG6T3/"},{"name":"GLSA-202312-06","tags":["vendor-advisory","x_transferred"],"url":"https://security.gentoo.org/glsa/202312-06"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-10-15T17:09:39.490416Z","id":"CVE-2021-29463","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-15T17:14:39.960Z"}}]}}
