An unspecified module in Huawei eSpace U1910, U1911, U1930, U1960, U1980, and U1981 unified gateways with software before V200R003C00SPC300 does not properly initialize memory when processing timeout messages, which allows remote attackers to cause a denial of service (out-of-bounds memory access and device restart) via unknown vectors.
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.
