CVE-2020-36328

Se encontró un fallo en libwebp en versiones anteriores a 1.0.1. Un desbordamiento del búfer en la región heap de la memoria en la función WebPDecodeRGBInto es posible debido a una verificación no válida del tamaño del búfer. La mayor amenaza de esta vulnerabilidad es la confidencialidad e integridad de los datos, así como la disponibilidad del sistema

A flaw was found in libwebp. A heap-based buffer overflow in functions WebPDecode*Into is possible due to an invalid check for buffer size. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

The libwebp packages provide a library and tools for the WebP graphics format. WebP is an image format with a lossy compression of digital photographic images. WebP consists of a codec based on the VP8 format, and a container based on the Resource Interchange File Format. Webmasters, web developers and browser developers can use WebP to compress, archive, and distribute digital images more efficiently. Issues addressed include buffer overflow and use-after-free vulnerabilities.
