CVE-2025-57812
[BIGSLEEP-434612419] CUPS-Filters has heap-buffer-overflow write in `cfImageLut()`
Description
CUPS is a standards-based, open-source printing system, and `libcupsfilters` contains the code of the filters of the former `cups-filters` package as library functions to be used for the data format conversion tasks needed in Printer Applications. In CUPS-Filters versions up to and including 1.28.17 and libscupsfilters versions 2.0.0 through 2.1.1, CUPS-Filters's `imagetoraster` filter has an out of bounds read/write vulnerability in the processing of TIFF image files. While the pixel buffer is allocated with the number of pixels times a pre-calculated bytes-per-pixel value, the function which processes these pixels is called with a size of the number of pixels times 3. When suitable inputs are passed, the bytes-per-pixel value can be set to 1 and bytes outside of the buffer bounds get processed. In order to trigger the bug, an attacker must issue a print job with a crafted TIFF file, and pass appropriate print job options to control the bytes-per-pixel value of the output format. They must choose a printer configuration under which the `imagetoraster` filter or its C-function equivalent `cfFilterImageToRaster()` gets invoked. The vulnerability exists in both CUPS-Filters 1.x and the successor library libcupsfilters (CUPS-Filters 2.x). In CUPS-Filters 2.x, the vulnerable function is `_cfImageReadTIFF() in libcupsfilters`. When this function is invoked as part of `cfFilterImageToRaster()`, the caller passes a look-up-table during whose processing the out of bounds memory access happens. In CUPS-Filters 1.x, the equivalent functions are all found in the cups-filters repository, which is not split into subprojects yet, and the vulnerable code is in `_cupsImageReadTIFF()`, which is called through `cupsImageOpen()` from the `imagetoraster` tool. A patch is available in commit b69dfacec7f176281782e2f7ac44f04bf9633cfa.

Action Type Old Value New Value Added Translation Title: libcupsfilters de OpenPrinting, Description: CUPS es un sistema de impresión de código abierto basado en estándares, y 'libcupsfilters' contiene el código de los filtros del antiguo paquete 'cups-filters' como funciones de biblioteca para ser utilizadas en las tareas de conversión de formato de datos necesarias en las Aplicaciones de Impresora. En CUPS-Filters versiones hasta e incluyendo 1.28.17 y libscupsfilters versiones 2.0.0 a 2.1.1, el filtro 'imagetoraster' de CUPS-Filters tiene una vulnerabilidad de lectura/escritura fuera de límites en el procesamiento de archivos de imagen TIFF. Mientras que el búfer de píxeles se asigna con el número de píxeles multiplicado por un valor de bytes por píxel precalculado, la función que procesa estos píxeles se llama con un tamaño del número de píxeles multiplicado por 3. Cuando se pasan entradas adecuadas, el valor de bytes por píxel puede establecerse en 1 y se procesan bytes fuera de los límites del búfer. Para activar el error, un atacante debe emitir un trabajo de impresión con un archivo TIFF manipulado, y pasar opciones de trabajo de impresión apropiadas para controlar el valor de bytes por píxel del formato de salida. Deben elegir una configuración de impresora bajo la cual el filtro 'imagetoraster' o su función C equivalente 'cfFilterImageToRaster()' sea invocado. La vulnerabilidad existe tanto en CUPS-Filters 1.x como en la biblioteca sucesora libcupsfilters (CUPS-Filters 2.x). En CUPS-Filters 2.x, la función vulnerable es '_cfImageReadTIFF() in libcupsfilters'. Cuando esta función es invocada como parte de 'cfFilterImageToRaster()', el llamador pasa una tabla de búsqueda durante cuyo procesamiento ocurre el acceso a memoria fuera de límites. En CUPS-Filters 1.x, las funciones equivalentes se encuentran todas en el repositorio cups-filters, el cual aún no está dividido en subproyectos, y el código vulnerable está en '_cupsImageReadTIFF()', el cual es llamado a través de 'cupsImageOpen()' desde la herramienta 'imagetoraster'. Un parche está disponible en el commit b69dfacec7f176281782e2f7ac44f04bf9633cfa. -
