Descriptions

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. 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 print 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 printing the image ICC profile, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p C`). The bug is fixed in version v0.27.5.

Exiv2 es una utilidad de línea 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 encontró una lectura fuera de límites. La lectura fuera de límites es desencadenada cuando Exiv2 es usado para imprimir los metadatos de un archivo de imagen diseñado. Un atacante podría explotar potencialmente la vulnerabilidad para causar una denegación de servicio, si puede engañar a la víctima para que ejecute Exiv2 en un archivo de imagen diseñado. Tenga en cuenta que este bug sólo es desencadenado cuando se imprime el perfil ICC de la imagen, que es una operación de Exiv2 que es usada con menos frecuencia y que requiere una opción adicional en la línea de comandos ("-p C"). El bug es corregido en versión v0.27.5
