Descriptions

An integer overflow in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (SIGSEGV) via a crafted PNG image file, because PngImage::readMetadata mishandles a chunkLength - iccOffset subtraction.

Un desbordamiento de enteros en Exiv2 hasta la versión 0.27.1, permite a un atacante causar una denegación de servicio (SIGSEGV) por medio de un archivo de imagen PNG creado, debido a que PngImage::readMetadata maneja de manera inapropiada una sustracción chunkLength - iccOffset.
