CVE-2026-69242

Full vulnerability record from the local CVENow database.

Description

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, a crafted many-band TIFF processed through VipsForeignLoadTiff can evade scanline validation in libvips/iofuncs/image.c and cause an integer overflow in vips_image_sanity. The resulting buffer-region calculation can access attacker-controlled negative offsets in mmap-resident allocations, allowing reads or writes of other image data, possible data disclosure through uncompressed .v output, and likely process crashes. Remote code execution has not been demonstrated but cannot be ruled out. This issue is fixed in version 8.18.3.

      "value": "libvips es una biblioteca de procesamiento de imágenes rápida con bajas necesidades de memoria. Antes de la versión 8.18.3, un TIFF de múltiples bandas manipulado procesado a través de VipsForeignLoadTiff puede evadir la validación de línea de escaneo en libvips/iofuncs/image.c y causar un desbordamiento de entero en vips_image_sanity. El cálculo resultante de la región del búfer puede acceder a desplazamientos negativos controlados por el atacante en asignaciones residentes en mmap, permitiendo lecturas o escrituras de otros datos de imagen, posible divulgación de datos a través de la salida .v sin comprimir, y probables fallos del proceso. La ejecución remota de código no ha sido demostrada pero no puede descartarse. Este problema está solucionado en la versión 8.18.3."
