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."},{"lang":"es","value":"Exiv2 es una biblioteca C++ y una utilidad de línea de comandos para leer, escribir, eliminar y modificar

leer, escribir, eliminar y modificar los metadatos de archivos de imagen. La lectura fuera de límites es desencadenada cuando es usado Exiv2 para escribir metadatos en un archivo de imagen diseñado. Un atacante podría explotar la vulnerabilidad para causar una denegación de servicio al bloquear Exiv2, si puede engañar a la víctima de ejecutar Exiv2 en un archivo de imagen diseñado. Nota que este bug solo es desencadenado al escribir los metadatos, que es una operación Exiv2 que es usado con menos frecuencia que la lectura de los metadatos. Por ejemplo, para desencadenar el bug en la aplicación de línea de comandos Exiv2, necesita agregar un argumento de línea de comando adicional como \"insert\". El bug es corregido en versión v0.27.4. Véase nuestra política de seguridad para
