CVE-2026-70653

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, the old-style Radiance RLE decoder in libvips/foreign/radiance.c can process a repeat marker at the beginning of a scanline in scanline_read_old and read q[-1] before any prior pixel exists. A crafted Radiance image loaded through VipsForeignLoadRad can therefore disclose four bytes of adjacent heap data, most likely other image data. This issue is fixed in version 8.18.3.

Summary		(es) libvips es una biblioteca rápida de procesamiento de imágenes con bajas necesidades de memoria. Antes de la versión 8.18.3, el decodificador RLE de Radiance de estilo antiguo en libvips/foreign/radiance.c puede procesar un marcador de repetición al principio de una línea de escaneo en scanline_read_old y leer q[-1] antes de que exista cualquier píxel anterior. Una imagen Radiance manipulada cargada a través de VipsForeignLoadRad puede, por lo tanto, divulgar cuatro bytes de datos de pila adyacentes, muy probablemente otros datos de imagen. Este problema está corregido en la versión 8.18.3.
