A memory corruption vulnerability exists in NextCloud Desktop Client v2.6.4 where missing ASLR and DEP protections in for windows allowed to corrupt memory.
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.
The product writes data past the end, or before the beginning, of the intended buffer.
