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."}, {"lang": "es", "value": "CUPS es un sistema de impresi\u00f3n de c\u00f3digo abierto basado en est\u00e1ndares, y 'libcupsfilters' contiene el c\u00f3digo de los filtros del antiguo paquete 'cups-filters' como funciones de biblioteca para ser utilizadas en las tareas de conversi\u00f3n 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 l\u00edmites en el procesamiento de archivos de imagen TIFF. Mientras que el b\u00fafer de p\u00edxeles se asigna con el n\u00famero de p\u00edxeles multiplicado por un valor de bytes por p\u00edxel precalculado, la funci\u00f3n que procesa estos p\u00edxeles se llama con un tama\u00f1o del n\u00famero de p\u00edxeles multiplicado por 3. Cuando se pasan entradas adecuadas, el valor de bytes por p\u00edxel puede establecerse en 1 y se procesan bytes fuera de los l\u00edmites del b\u00fafer. Para activar el error, un atacante debe emitir un trabajo de impresi\u00f3n con un archivo TIFF manipulado, y pasar opciones de trabajo de impresi\u00f3n apropiadas para controlar el valor de bytes por p\u00edxel del formato de salida. Deben elegir una configuraci\u00f3n de impresora bajo la cual el filtro 'imagetoraster' o su funci\u00f3n 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 funci\u00f3n vulnerable es '_cfImageReadTIFF() in libcupsfilters'. Cuando esta funci\u00f3n es invocada como parte de 'cfFilterImageToRaster()', el llamador pasa una tabla de b\u00fasqueda durante cuyo procesamiento ocurre el acceso a memoria fuera de l\u00edmites. En CUPS-Filters 1.x, las funciones equivalentes se encuentran todas en el repositorio cups-filters, el cual a\u00fan no est\u00e1 dividido en subproyectos, y el c\u00f3digo vulnerable est\u00e1 en '_cupsImageReadTIFF()', el cual es llamado a trav\u00e9s de 'cupsImageOpen()' desde la herramienta 'imagetoraster'.
