Multiple buffer overflows in OpenTTD before 1.1.3 allow local users to cause a denial of service (daemon crash) or possibly gain privileges via (1) a crafted BMP file with RLE compression or (2) crafted dimensions in a BMP file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
