Descriptions

The DGifDecompressLine function in dgif_lib.c in GIFLIB (possibly version 3.0.x), as later shipped in cgif.c in sam2p 0.49.4, has a heap-based buffer overflow because a certain "Private->RunningCode - 2" array index is not checked. This will lead to a denial of service or possibly unspecified other impact.

La función DGifDecompressLine en dgif_lib.c en GIFLIB (probablemente en la versión 3.0.x), tal y como se distribuyó posteriormente en cgif.c en sam2p 0.49.4, tiene un desbordamiento de búfer basado en memoria dinámica (heap) debido a que no se comprueba cierto índice de arrays "Private->RunningCode - 2". Esto podría conducir a una denegación de servicio (DoS) o a otro tipo de impacto sin especificar.
