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."}, {"lang": "es", "value": "Exiv2 es una utilidad de l\u00ednea de comandos y una biblioteca C++ para leer, escribir, borrar y modificar los metadatos de los archivos de imagen. El fallo de aserci\u00f3n es desencadenado cuando Exiv2 es usado para modificar los metadatos de un archivo de imagen dise\u00f1ado. Un atacante podr\u00eda explotar potencialmente la vulnerabilidad para causar una denegaci\u00f3n de servicio, si puede enga\u00f1ar a la v\u00edctima para que ejecute Exiv2 en un archivo de imagen dise\u00f1ado. Tenga en cuenta que este bug s\u00f3lo es desencadenado cuando se modifican los metadatos, que es una operaci\u00f3n de Exiv2 que es usada con menos frecuencia que la lectura de los metadatos. Por ejemplo, para desencadenar el bug en la aplicaci\u00f3n de l\u00ednea de comandos de Exiv2, es necesario a\u00f1adir un argumento extra en la l\u00ednea de comandos como \"fi\". ### Parches El bug ha sido corregido en la versi\u00f3n v0.27.5. ### Referencias Prueba de regresi\u00f3n y correcci\u00f3n de bug: #1739 ### Para m\u00e1s informaci\u00f3n Consulte nuestra [pol\u00edtica de seguridad](https://github.com/Exiv2/exiv2/security/policy) para obtener informaci\u00f3n sobre la seguridad de Exiv2"}], "lastModified": "2023-12-22T10:15:09.603", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:exiv2:exiv2:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "511F5B8C-FF2B-434C-8C9C-DC1140F35CBC", "versionEndIncluding": "0.27.4"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:fedoraproject:fedora:33:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E460AA51-FCDA-46B9-AE97-E6676AA5E194"}, {"criteria": "cpe:2.3:o:fedoraproject:fedora:34:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A930E247-0B43-43CB-98FF-6CE7B8189835"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "07B237A9-69A3-4A9C-9DA0-4E06BD37AE73"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
