Code execution via wrapped request buffer allocation
Published Feb 9, 2022 · Updated Aug 3, 2024
Integer overflow in Distributed Data Systems IGSS Data Server 15.0.0.22020 and earlier allows remote attackers to execute code via crafted messages. When a request is appended to a buffered request, attacker-controlled 32-bit sizes wrap before realloc, producing a small heap allocation that memcpy then overruns. The service accepts the messages without authentication; successful exploitation crashes the server or executes arbitrary code.
