An out-of-bounds read was found in Exiv2 versions v0.27.4 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 v0.27.5."}, {"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. En versiones v0.27.4 y anteriores a Exiv2 se encontr\u00f3 una lectura fuera de l\u00edmites. La lectura fuera de l\u00edmites es desencadenada cuando Exiv2 es usado para escribir metadatos en un archivo de imagen dise\u00f1ado. Un atacante podr\u00eda explotar potencialmente la vulnerabilidad para causar una denegaci\u00f3n de servicio al bloquear Exiv2, 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 escriben 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 adicional en la l\u00ednea de comandos, como por ejemplo insert.
