The Micro Focus Client for OES before version 2 SP4 IR8a has a vulnerability that could allow a local attacker to elevate privileges via a buffer overflow in ncfsd.sys.
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.
