Under certain conditions a malicious user provoking an out of bounds buffer overflow can prevent legitimate users from accessing the SAP Internet Graphics Server (IGS), 7.20, 7.20EXT, 7.45, 7.49, 7.53.
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.
